Summary form only given.During the last decade, there has been considerable interest in the photonic bandgap materials or photonic crystals. Now, at least for two-dimensional structures, the potential ability of photon control is being successfully demonstrated in the optical regime. Lasing actions from two-dimensional photonic crystal structures are realized by a few groups. The first reported laser structure is a freestanding slab in the air. Very recently, our group has introduced a photonic crystal slab structure on the low-index material to improve the thermal property. In this work, we report the InGaAsP lasing characteristics of the photonic crystal cavity of various geometries and the enhanced extraction of spontaneous emission from the photonic crystal pattern.
