  • Abstract: We demonstrate compressive sensing of the eight-dimensional reflectance field (RF), which describes spatial and angular information of light rays toward and from an object. The RF is also known as the Bidirectional Scattering Surface Reflectance Distribution Function (BSSRDF). In this method, incident rays and reflected rays to/from the object are modulated by variable coding masks, and the modulated rays are multiplexed onto an image sensor. The images captured with multiple mask patterns are decoded by a compressive sensing algorithm. The RF of the object was successfully reconstructed from less than half of the number of measurements required with conventional methods.

  • Abstract: We report numerical and experimental results obtained with an optical setup that simulates the heating and cooling processes expected in a multi-slab high-average-power laser head. We tested the performance of an adaptive optics system consisting of a photo-controlled deformable mirror and a Shack-Hartmann wavefront sensor for effective correction of the generated wavefront aberrations.

  • Abstract: Solution processed silver nanowire-indium tin oxide nanoparticle (AgNW-ITONP) composite thin films were successfully applied as the transparent electrodes for Cu(In,Ga)Se2 (CIGS) thin film solar cells with ZnS buffer layers. Properties of the AgNW-ITONP thin film and its effects on performance of CIGS/ZnS thin film solar cells were studied. Compared with the traditional sputtered ITO electrodes, the AgNW-ITONP thin films show comparable optical transmittance and electrical conductivity. Furthermore, the AgNW-ITONP thin film causes no physical damage to the adjacent surface layer and does not need high temperature annealing, which makes it very suitable to use as transparent conductive layers for heat or sputtering damage-sensitive optoelectronic devices. By using AgNW-ITONP electrodes, the required thickness of the ZnS buffer layers for CIGS thin film solar cells was greatly decreased.

  • Abstract: Efficient amplification of coherent short-wavelength pulses along a plasma gain column requires traveling-wave excitation with the sweep velocity matched to the signal group velocity. Through simulations incorporating the gain dynamics of the system we show that the group velocity is not constant but monotonously increases along the line focus due to strong saturation. We demonstrate a line-focusing configuration that results in traveling wave excitation with the sweep velocity well matched to the spatially varying group velocity. Moreover, we show through numerical simulations that the improved velocity matching yields a significant improvement in signal amplification.

  • Abstract: Abstract We analyze how to obtain circular polarized light with a high polarization degree and a high stability using a system composed by two waveplates. The configurations studied involve half and quarter waveplates. We show how the high polarization degree is achieved using a λ/2+λ/4 configuration. However the highest stability under small variations in the azimuths of the waveplates is obtained employing a λ/4+λ/2 configuration. Analytical calculus are particularized for quartz and MgF₂ waveplates are presented.

  • Abstract: We present a thermal rectification device concept based on far-field radiative exchange between two selective emitters. Rectification is achieved due to a large contrast between the two selective emitters thermo-optical properties. A simple device constituted by two Fabry-Pérot cavities made of metallic (Au) and semiconductor (Si and HDSi) thin films is proposed. This device is the first rectifier based on photonic structures.It shows a rectification ratio increasing with temperature up to 19% for a temperature difference ΔT = 370 K. Presented results might be useful for energy conversion devices, smart radiative coolers / insulators engineering and thermal logical circuits development.

Hyperspectral or multi-spectral: Spectral interdependence of remote-sensing reflectance and its implications on the design of ocean color satellite sensors

  • Abstract: Using 845 remote-sensing reflectance spectra (Rrs(λ), sr-1, λ from 400 to 700 nm with a 5-nm resolution), we evaluated the correlations of Rrs(λ) between neighboring spectral bands in order to characterize 1) the spectral interdependence of Rrs(λ) at different bands and 2) to what extent can hyperspectral Rrs(λ) be re-constructed from multi-band measurements. The 845 Rrs spectra were measured over a wide variety of aquatic environments where water color varied from oceanic blue to coastal green or brown, with chlorophyll-a concentrations ranging from ~0.02 to >100 mg m-3, bottom depths from ~1 m to > 1000 m, and bottom substrates including sand, coral reef, and seagrass. The correlation coefficient of Rrs(λ) between neighboring bands (λk and λl), rΔλ(λk,λl), was evaluated systematically, with the spectral gap (Δλ= λl - λk) changing from 5, 10, 15, 20, 25, to 30 nm, respectively. It was found that rΔλ decreased with increasing Δλ, but remained > 0.97 for Δλ ≤ 20 nm for all spectral bands. Further, using 15 spectral bands between 400 and 710 nm, we re-constructed, via multi-variant linear regression, hyperspectral Rrs(λ) (from 400 to 700 nm with a 5-nm resolution). The coefficient of variation between measured and re-constructed Rrs for each band between 400 and 700 nm was generally less than 2%, with a correlation coefficient close to 1.0. The mean absolute error between measured and re-constructed Rrs was about 0.00005 sr-1 for each band, which is significantly smaller than the Rrs uncertainties from all past and current ocean color satellite measurements. These results echo findings of earlier studies that Rrs measurements at ~15 spectral bands in the visible domain can provide nearly identical spectral information as with hyperspectral (contiguous bands at 5-nm spectral resolution) measurements. Such results provide insights for data storage and handling of large volume hyperspectral data as well as for the design of future ocean color satellite sensors.

  • Abstract: A novel design of single photon avalanche photodiode (SPAD) is proposed based on resonant cavity (RC) structure and its performance is studied. In the proposed structure, InAlAs/InGaAs distributed Bragg reflectors (DBR) are employed as top and bottom mirrors and the quantum efficiency (QE) of absorption region is calculated for absorption region considering the effect of RC. Results show that using 12 periods of DBRs as bottom reflector without incorporation of top mirror can enhance the QE to about 90% at room temperatures. For this RC-enhanced SPAD, a single photon quantum efficiency (SPQE) is obtained about 0.35 at T=300K. For temperatures lower than T=260K, SPQE is about 1. Results show that although the RC doesn’t affect the dark current, however for a given SPQE the dark count rate is lower for RC-SPAD.

  • Abstract: In this paper, the plasmonic directional coupler (PDC) with 90º waveguide bends has been numerically analyzed by the finite-difference time-domain (FDTD) method, considering the nonlinear response of metal due to the ponderomotive force. It has been shown that the required switching power of the PDC is 0.05% of that of the case that only the dielectric is nonlinear and the nonlinearity of metal is neglected. Also, the cross-phase modulation nonlinear effect has been investigated and the power for switching is decreased significantly compared to the one with the self-phase modulation effect.

  • Abstract: To expand and investigate the potential of spectral imaging, we developed a portable multispectral system using light-emitting diodes. This system recovers spectral information from the ultraviolet to the near infrared over a large area using two different image sensors synchronized with 23 bands of illumination. The system was assessed for spectral reconstruction through simulations and experimental measurements by means of two methods of spectral reconstruction and three different evaluation metrics. The results over a Macbeth color checker chart and other samples, including pigments usually employed in art paintings, are compared and discussed. The portable multispectral system using light-emitting diodes constitutes a cost-effective and versatile method for spectral imaging.

  • Abstract: A structured-light system with binary defocusing technique has potential to have more extensive application due to its high speeds, gamma calibration free and no rigid synchronization requirement between the camera and projector. However, the existing calibration methods fail to achieve high accuracy for a structured light system with an out-of-focus projector. This paper proposes a method that can accurately calibrate a structured light system even when the projector is not in focus, making it possible for high-accuracy and high-speed measurement with the binary defocusing method. Experiments demonstrate that a root-mean-square (rms) error of 77 $\mu$m can be achieved with a calibration volume of $150(H)\times 250(W)\times 200(D) mm^3$

  • Abstract: Corner cube was firstly theoretically and experimentally proved to be a peculiar coherent combination element by the author, which can contribute to improve the laser far-field energy focalization when it is used as a retro-reflecting mirror in the solid state lasers. Furthermore the differences between the coherent characteristics of the lasers with corner cube resonator (CCR) and F-P resonator were investigated respectively. Theoretical calculation and numerical simulation have proved that the symmetric outputs of the CCR laser are coherent and the adjacent outputs are partially coherent. Based on these special coherent characteristics, a new laser coherent combining structure in which a corner cube was utilized as the terminal mirror was proposed and experimentally investigated. In our experiment, the far-field power distribution measured of the laser array coherent combing is good agreement with the theoretical calculation. This novel coherent characteristics of corner cube may be important for the applications in the solid-state lasers and the laser coherent combining systems, and it may be one of the develop trends and future research directions for CCR lasers.

  • Abstract: The effects of different pitch and angle of gradual-triangle Lenticular lens for the point-blank LED fog lamp was investigated under the standard of ECE R19. The novel LED fog lamp was assembled of point-blank LED light source, parabolic reflector and a gradual-triangle Lenticular lens. A light tracing analysis was used for the design of the gradual-triangle Lenticular lens. The pitch, which varied from 1 to 6 mm, and the apex angle, which changed from 5 to 32 degrees, were both investigated in regard to the gradual-triangle Lenticular lens. The optimum pitch was 5mm, and the efficiency of the lamp system and Lenticular lens could reach 93% and 98.1% by simulation, respectively. The results of experiment had over 94% similar to that of simulation by normalized cross correlation (NCC) for the light intensity. © 2014 Optical Society of America

  • Abstract: The optimization of dwell time is an important procedure in deterministic subaperture polishing. We present a modified optimization model of dwell time by iterative and numerical method, assisted by extended surface form and tool path for suppressing the edge effect. Compared with discrete convolution and linear equation models, the proposed model has essential compatibility to arbitrary tool paths, multiple tool influence functions (TIFs) in one optimization and asymmetric TIFs. The emulational fabrication of a Ф200mm workpiece by the proposed model yields a smooth, continuous and nonnegative dwell time map with a root-mean-square (RMS) convergence rate of 99.6%, and the optimization cost much less time. By the proposed model, influences of TIF size and path interval to convergence rate and polishing time are optimized respectively for typical low and middle spatial frequency errors. Results show that (i) the TIF size is nonlinear inversely proportional to convergence rate and polishing time. A TIF size of ~1/7 the workpiece size is preferred; (ii) the polishing time is less sensitive to path interval, but increasing the interval markedly reduces the convergence rate. A path interval of ~1/8-1/10 of the TIF size is deemed to be appropriate. The proposed model is deployed on a JR-1800 and MRF-180 machine. Figuring Results of Φ920mm Zerodur paraboloid and Φ100mm Zerodur plane by them yield RMS of 0.016λ and 0.013λ (λ=632.8nm) respectively, thereby validate the feasibility of proposed dwell time model used for subaperture polishing.

  • Abstract: Laser filter and color filter used in slit lamp delivery have been developed by rugate approach to improve color rendition of illumination for retinal photocoagulation. The double-notch laser filter is designed according to the required laser lines and incident angle. Based on the transmission spectrum of double-notch laser filter and the spectral power distribution (SPD) of the light source of slit lamp, a scanning search algorithm is applied to find the optimal transmission spectrum of multi-notch color filter for the best color rendition index of illumination. An open-source software is used to design the refractive index profile of all the rugate filters which are deposited by the reactive pulse magnetron sputtering. The SPD of slit lamp delivery which will use the deposited double-notch laser filter and multi-notch color filter is also calculated to demonstrate that the color rendition property of illumination can be improved remarkably, thus making fundus observation and retinal laser photocoagulation more reliable and efficient.

  • Abstract: An octagonal photonic crystal fiber (O-PCF) with elliptical shape in the centre core is numerically investigated for residual dispersion compensation in the wavelength range of 1460 – 1675 nm. The designed fiber exhibits flattened negative dispersion over S + C + L + U wavelength bands and average dispersion of – 465.5 ps/(nm.km) with absolute dispersion variation of 10.5 ps/(nm.km). Besides the proposed PCF shows a high birefringence of 2.68×10-2 at the operating wavelength 1550 nm which meet the requirement of high birefringence. Moreover, variation of two air-holes in the first ring up to 5% ensures average dispersion of – 491.5 ps/(nm.km) with dispersion variation of 13 ps/(nm.km) and birefringence reaches up to 3×10-2. Furthermore, to evaluate the sensitivity of the fiber dispersion properties, ±5% variation in the optimum parameters is studied.
