Band-gap can be observed for TM polarization and compared with the simple lattice structure based on the same material, the band-gap is increased by 62.7%. By optimizing the parameters we get the PCW with the propagation only near the wavelength of 1.55 μm and a flat group index curve in a wide wavelength range of 40 nm. And the group velocity dispersion compensation can be realized by the structure optimization. The results provide a reference for the study and application of photonic crystal waveguide based on the compound lattice structure. Hits: 3665 Download times: 215 View Full Text    Download reader
