摘要：
In this paper, we report the designs of optical logic AND gates in Y shaped photonic crystal waveguides based on two structures, one of which is a hexagonal lattice with silicon rods in air (SRA) and another is the hexagonal lattice arrangement of air holes in silicon (AHS). The structure has been analyzed by plane wave expansion (PWE) method and simulated using finite difference (FDTD) method. It has been analyzed that the bit rate for SRA structure is 2.016Tbit/s and for the AHS structure is 1.785Tbit/s. Thus, the proposed photonic crystal structures could really work as an efficient optical logic AND gates.
