In a white light cavity (WLC), the group velocity is superluminal over a finite bandwidth. For a WLC-based data buffering system we recently proposed, it is important to visualize the behavior of pulses inside such a cavity. The conventional plane wave transfer functions, valid only over space that is translationally invariant, cannot be used for the space inside WLC or any cavity, which is translationally variant. Here, we develop the plane wave spatio temporal transfer function (PWSTTF) method to solve this problem, and produce visual representations of a Gaussian input pulse incident on a WLC, for all times and positions.

  13. In modeling a FP, it is customary to consider each mirror to have an anti-reflection coating on one face, and a partially reflecting surface on the other. However, in reality, the partial reflectivity is produced by using layers of dielectric materials. Thus, in order to model properly any potential phase shift, in reflection or transmission at such an interface, it is necessary to take into account the presence of such a layer, which can be considered to be a Bragg grating. When this is done, it is no longer necessary to consider the presence of another surface with an anti-reflection coating.

  16. To calculate the phase shift due to the Bragg reflection, we solved the coupled equations presented in Ref. 14 for the case of λ(wavelength) = 1550nm, θ(angle of incidence) = 0, ϕ(slant grating angle) = 0 and σ(conductivity) = 0. The modulated dielectric constant is assumed to be of the form ε=ε0+ε1cos[(2π/Λ)z]where ε0 is the average dielectric permittivity, ε1is the modulation amplitude and Λ is the grating period. Λ is chosen to fulfill the Bragg matched condition. We have found that the phase shift for the reflected beam is a constant of −π/2, independent of the value of ε1, which determines the amplitude of the reflectivity. We also found that there is no phase shift for the transmitted wave. Finally, we assumed that the thickness of each BG is infinitesimally small, so that ΔνBragg≫ΔνFWHMwhere ΔνBraggis a bandwidth of the Bragg reflection and ΔνFWHMis a full width half maximum of the FP cavity. Thus, for a particularε1, the Bragg reflection coefficient can be expressed as exp(−jπ/2)Rwith a constant value of R, within the spectral range ofΔνFWHM.
