Abstract

In this paper, the performance of an on-chip hollow-core-waveguide (HW) using high-contrast gratings (HCG) for analog signal transmission is analyzed numerically. Simulation results indicate that after propagating 100 m in a HCG-HW with optimally designed parameters, there is very little degradation of either third-order intermodulation distortion spur-free dynamic range (IM3 SFDR) or third-order harmonic distortion (THD) SFDR. Due to the chromatic dispersion of the HCG-HW, the highest second-order harmonic distortion (SHD) SFDR is limited to 107.3 dB ·Hz<sup>1/2</sup>. In addition, > 100 dB ·Hz <sup>2/3</sup> IM3 SFDR can be achieved over a radio frequency (RF) range of 80 GHz and an optical wavelength bandwidth of 50 nm after propagation 100 m through a HCG-HW. The parameter dependence of the waveguide performance is also investigated. With a ±20 nm variation on all parameters, the propagation length in an HCG-HW is limited to ~6 m in order to maintain an IM3 SFDR of >100 dB ·Hz<sup>2/3</sup>.
