We have microfabricated 2-D photonic bandgap structures in a thin slab of dielectric material to define reflectors and high-Q microresonators. By selectively omitting holes from the two-dimensional photonic crystal, laser cavities and optical resonator switches can be defined. We have designed this structure with a finite difference time domain (FDTD) approach, and demonstrate some promising designs in InGaAs/InGaAsP multiple quantum well material with emission wavelength of 1.55 microns.
