Abstract

In this paper, we present the design of All-optical OR logic gate based on 2-D (two dimension) photonic crystals. To realize this, we consider the photonic crystals (PCs) with a square lattice of dielectric rods (refractive index=3. 40). These rods are surrounded by air (refractive index=1). First we design the structure using the Finite Difference Time Domain (FDTD) method and in second step, we compute the band gap by plane wave expansion (PWE) method. These methods are kept to analyze the behavior of the structure. Band gap width is 0. 2516 and normalized central frequency of band gap is 0. 6451. Overall size of the logic gate designed is 13µm * 8µm i. e. 104 µm2 with the lattice constant 540 nm.
