Abstract: In this paper, all optical OR, AND, NOR and NAND gates based on linear photonic crystals (LPhCs) have been numerically designed and simulated by the plane wave expansion (PWE) and finite difference time domain (FDTD) methods. The LPhC fundamental structure with cross-section of 114 μ m 2 is used for designing the proposed all optical gates (AOGATEs), which is composed of 15 × 23 cubic matrix of dielectric silicon rods in air substrate. The mechanism of the proposed AOGATEs is performed based on phase shift keying (PSK) technique and beam interference effect. Simulation results by FDTD approach illustrate the minimum contrast ratio of 8.88 and 10.31 dB for all optical AND/NOR and OR/NAND logic gates, respectively. Also, the minimum bit rate is obtained as 3.34 Tb/s for AND/NOR and 5 Tb/s for OR/NAND logic gates. [ABSTRACT FROM AUTHOR]
