Abstract

We propose and numerically investigate a new all-optical OR gate based on a two-dimensional triangular-lattice photonic crystal. The device is composed of a hexagon- shaped ring resonator waveguide with two input ports and one output port in silicon rods embedded in air. Transmission behaviors of the proposed device are investigated by the finite difference time domain method. The logic OR gate can work at two wavelengths of 1.34 and 1.38 μm and is potentially applicable for photonic integrated circuits..
