Design and analysis of all-optical 4–2 binary encoder based on photonic crystal

Design and analysis of all-optical 4–2 binary encoder based on photonic crystal In this paper we theoretically propose combining optical waveguides with nonlinear photonic crystal based ring resonators for realizing an all optical 4–2 encoder. Nonlinear resonant rings are constructed from GaAs as the material used for dielectric rods. By application of optical beam to input ports of the structure the on/off states are realized and the resulting truth table confirms functionality of proposed device. The switching threshold and time delay of the device are about 1 kW/µm2 and 1 ps, respectively. The normalized power at the output ports for all the ports in ON states is the same and equal to 60%.
