Abstract
Abstract An all optical Gray-to-binary coded decimal (BCD) converter was proposed using nonlinear ring resonators inside square lattice photonic crystals. The proposed structure works based on threshold switching inside nonlinear resonators. The other advantage of the proposed structure is reducing its time response delay. The mean amount of normalized power at the output ports for logic 1 is about 90 %. Also the delay time is about 1 ps.
