Abstract

A photonic crystal with defects will appear some localized modes in photonic frequency gap,and the linear defects will cause the formation of a waveguide with high transmission efficiency.The photonic band structure and the density of the state of a two-dimensional square lattice photonic crystals with Al rotating square cylinders in air were calculated.The waveguide characteristics and its electric field distribution of TM mode were analyzed,and the transmission efficiency of waveguide coupling was discussed.
