We report all-optical regeneration in chalcogenide glass (As2S3) waveguides integrated with Bragg gratings, demonstrating nonlinear power transfer functions with 1ps to 2ps optical pulses. We investigate several different ...

In this paper, we have used the finite-difference time-domain (FDTD) method to analyze the optical pulse propagation in a nonlinear, one-dimensional photonic crystal (1DPC). Hyperbolic secant pulses with various carrier wavelengths are utilized...
