In this paper an all-optical switch for logic gates application using two-dimensional (2D) Photonic Crystal (PC) waveguides based on phase difference between incident beams is proposed. A PC with triangular lattice of dielectric rods in the air is used as the main structure of the device. Ourconsidering devices are XOR and OR logic gates. The plan wave expansion method (PWE) is used tophotonic band gap (PBG) calculation, and finite-difference time-domain method (FDTD) is used tocompute electrical field distribution in the photonic devices. The designed gates can be used in the photonic integrated circuits.
