Abstract
An all-optical 1of 2 De-multiplexer (D-mux) based on silicon rods in the air, created by two dimensional square lattice photonic crystals (PCs), is proposed and demonstrated. The device operation is because of line and point defects and phase difference between input beams that created by point defects. The device has a selection line, S, an input data port, A, and three output data ports, Q0, Q1 and Q2. Photonic band gap (PBG) calculation is done by plane wave expansion (PWE) method and electrical field distribution (EFD) in the device by finite difference time domain (FDTD) method. Power levels lower than “0.25P0” is considered as “0” logic value and higher than “0.4P0” as “1” logic value. When SÂ =Â 0, the data of port A, is directed to Q0 and when SÂ =Â 1, is directed to Q1. Moreover, one of the output ports, Q1 or Q2, can be used as an AND logic gate. The device is applicable for all-optical processors and integrated circuit.
