摘要
We theoretically investigate the optical characteristics of a thin-film photonic crystal structure with a complete photonic bandgap for both polarization of the transverse electric and transverse magnetic modes for any in-plane direction. The structure consists of three-layer stacked two-dimensional photonic crystal slabs, and the thickness of the structure is less than a few wavelengths. We show that a wide complete photonic bandgap can be obtained in the asymmetrically stacked photonic crystal structure. In addition. we designed a waveguide with a broad bandwidth of 100 nm and a nanocavity with a quality factor of 3.7 x 10(7) in the structures.
