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.

In this paper an ultra-compact all-optical encoder is presented by using a two-dimensional photonic crystal. The designed logic gate is based on the interference effect. The proposed structure consists of several photonic crystal waveguides connected by 2 nano-resonators. The nano-resonators are designed to reduce the size of the radius of the dielectric rods. The contrast ratios and delay time for the proposed all-optical encoder are respectively 6 dB and 125 fs. The size of the structure is equal to 132 µm2. Equality of the output power in the logic states “one”, the small dimensions, the low delay time, compact and simple structure have shown that the logic gate is suitable for the using in optical integrated circuits.

AbstractIn this paper, we aim to design an all-optical structure that can be employed as optical OR/AND logic gates. To do so, a nonlinear photonic crystal-based ring resonator will be designed whose resonant wavelength depends on the variation of optical intensity. Then, by adding some optical waveguides, the optical logic circuit structure will be obtained that can function as optical OR/AND logic gates. The maximum time delay for the proposed structure is about 1.5 ps. Total footprint of the proposed structure is about 372 mm2. The proposed structure has lower time delay, lower footprint and lower optical input power compared with previously proposed structures.

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.
