## Abstract We have investigated the group delay and the dispersion of light propagating through photonic crystal (PhC) resonators defined in 240 nm thick GaAs membranes. The design of the resonators is based on a PhC heterostructure, which combines waveguide sections with different lattice constan
## Abstract We employ topology optimization with the finiteβelement method to improve the coupling between a slab waveguide and a photonic crystal waveguide. Here, we apply topology optimization in a small design region to realize the improvement of the coupling. Also, we simplify an optimized stru
