Abstract Optical logic gates can play crucial roles for designing all optical data processing circuits. Photonic crystals are one of the suitable platforms that can be used for designing all optical devices. In this paper an optical XOR gate was designed using nonlinear ring resonators. The proposed structure works are based on threshold switching. The working wavelength and the switching threshold of the resonators are 1550 nm and 1.8 W/μm2, respectively. The rise time is about 1 ps and the ON/OFF contrast ratio is about 16 dB.

Abstract All optical logic gates are building blocks for all optical data processors. One way of designing optical logic gates is using threshold switching which can be realized by combining an optical resonator with nonlinear Kerr effect. In this paper we showed that a novel structure consisting of nonlinear photonic crystal ring resonator which can be used for realizing optical NAND/NOR and majority gates. The delay time of the proposed NAND/NOR and majority gates are 2.5 ps and 1.5 ps respectively. Finite difference time domain and plane wave expansion methods were used for simulating the proposed optical logic gates. The total footprint of the proposed structure is about 988 μm2.
