Characterization of In-Plane Resonant Cavities with Photonic Crystal Boundaries Etched in InP-Based Heterostructure

In-plane cavities with photonic crystal boundaries are realized in InP/InGaAsP/InP slab waveguides. A quality factor of 400 for a 6 mum long cavity with 6-hole mirrors is measured. The quality of the photonic crystals are investigated by fitting transmission spectra with 2D finite-difference time-domain simulations
