Design and Simulation of All-Optical OR Logic Gate based on 2-D Photonic Crystal
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...

متن کاملAll optical 1 to 2 decoder based on photonic crystal ring resonator
In this paper we combined an optical mixer via photonic crystal ringresonator to propose an all optical 1 to 2 decoder. The main idea used in this paper isbased on controlling the optical behavior of the resonant ring via optical powerintensity. We know that resonant wavelength of the photonic crystal ring resonator isvery sensitive upon the refractive index of dielectric rods, on the other had...
متن کاملDesign and Characteristics of Photonic Crystal based Optical NOT Logic Gate
In this paper two –dimensional square shaped photonic crystal ring resonator based NOT logic gate is proposed. The numerical, structural, theoretical analysis is performed using 2D-FDTD method where simulation is done through an optical switch. This switch is composed of nonlinear PCRR and T-type waveguide. The dielectric rods used in air is of Indium Phosphide with refractive index of 3.1. Ban...
