Optical simulation of photonic crystal patterned layer lasers

The dispersion relation of a cavity surrounded by multi-layered photonic crystals is obtained using a fast, accurate and generalized round trip operator. This will assist in the optical design of photonic crystal patterned lasers. A 2D quasi-bandgap was obtained for the lowest order mode of a 1D multi-layered photonic crystal. Although the method is demonstrated for 1D photonic crystal layers, the method is general and can be extended to two dimensional systems.
