The trans-mission spectra show that the thickness of defects plays a key role in determining the trans-mittance of defect modes. When the thickness was ？180 nm, an obvious defect mode with the high transmittance of 55% and a narrow full width at half maximum of 18 nm was observed in the original photonic band gaps.
