Opis:: In this paper we will propose and design an all optical amplitude shift keying demodulator using a photonic crystal based nonlinear ring resonator. The proposed structure will be designed such that it can generate digital 0 and 1 based on the amplitude of the input signal. The working mechanism is based on controlling the optical behavior of the resonant ring using optical intensity. The proposed structure was simulated using plane wave expansion and finite difference time domain methods. The simulation results show that the rise and fall times for the proposed structure are 0.5 and 0.1 ps, respectively.

Opis:: Optical logics will play a crucial role in the next generation all optical data processing networks. Therefore an all optical majority gate will be designed by using nonlinear photonic crystal ring resonators. For realizing the proposed structure we need three nonlinear resonant rings. In order to make nonlinear resonant rings, we used chalcogenide glass as the dielectric material for the dielectric rods. The output port of the proposed structure will be active only when two or three logic input ports are active. The rise and fall time values of the proposed structure are about 2 and 1 ps, respectively. The total footprint of the proposed structure is about 1287 μm².
