An Optimized and Logic Gate with High Transmission and Low Losses Based on Y-junction

Abstract

We propose the optimization of a micro-component for the integrated optics which is the AND logic gate formed by a Y-junction based on two-dimensional crystal Photonics with a triangular lattice of air holes in silicon. We chose this structure to improve the transmission of single mode with high power and low losses compared to the AND logic gate classic, by optimizing the photonic crystal geometric parameters, the band gaps wavelength and eliminate the higher order modes in order to realize an optimized AND logic gate.
