In this paper, the use of the Kerr effect in a two-dimensional square lattice of In0.82Ga0.18As0.40P0.60 rods in photonic crystal proposes an ultra-compact all-optical NOT logic gate. The main device operation is based on the concept of all the optical switches. In our work, the novelty lies in the design of a new simple nonlinear ring based on the combination of silicon nano-crystal "Si–Nc/In0.82Ga0.18As0.40P0.60" materials that can be used. The contrast ratio and delay time for the proposed NOT logic gate are respectively 25.52 dB and 0.66 ps. The structure size is equal to 168 μm2. Designed logic gates are characterized by low energy consumption, high-speed response, compactness and easy integration. All simulations are based on Non-Linear-Finite Difference Time Domain (NL-FDTD) and Plane Wave Expansion (PWE) numerical methods.

Abstract The proposed research reports the simulation of a photonic crystal (PhC) ring-resonator-based full-optical NAND and NOR gate design. The designed structure comprises a 18 × 30 square lattice dielectric silicon rod-type PhC with a refractive index of n = 3.46. An interatomic distance ‘a’ of 560 nm, radius ‘r’ of 0.21a (0.133 μm) and input wavelength λ = 1550 nm with an input signal amplitude of 1 volt are used in this design. The proposed structure provides two large band gaps in Transverse Electric polarized mode in the ranges of 1342–1980 nm and 758–779 nm. Similar parameters are used for both NAND and NOR logic gate designs. The functionality of the proposed full-optical gates depends on the ring resonator principle and the intensity of the incident light. Numerical analysis of the simulation is based on the finite difference time domain method, whereas band gap analysis is performed using the plane wave expansion method.
