Abstract

The design of all-solid-state photonic crystals depends on the existence of wavelength-dependent bandgaps for transverse electric and transverse magnetic fields. We have used the effective index approximation for InP-based multilayer stack to simulate bands in 2D photonic crystals. We carried out dispersion bands simulations that yielded joint bandgaps and defect bands for hexagonal lattices of air holes with dielectric as background and honeycomb lattice of rods of dielectric with air as background. To make fabrication more practical, we also investigated the impact of replacing air in both designs with more rigid porous materials with slightly higher refractive index. 3D FDTD simulations for these designs show good confinement and low propagation losses in straight and curved waveguides.
