摘要
We present a novel proposal for an all-optical AND logic gate. It is designed based on line and point defects in two-dimensional photonic crystal (PC) rods in air with square lattice. Material of the rods is silicon with dielectric constant 11.56. Dimension of the proposed device is equal to 12.155x12.155 mu m. The device elaborated has a simple structure consisting of two inputs - a main output and two idler outputs. Bit rate of the device is equal to 3 center dot 10(12) bit/s. Maximum contrast ratio is 5.84 dB. It is a good candidate for optical integrated circuits.
