A 2D photonic bandgap single defect laser is demonstrated. For an active medium, six strain compensated InGaAsP quantum wells are employed because of the relatively small surface recombination velocity. To realize a mechanically robust structure with good thermal properties, the InGaAsP layer was fused with the AlAs layer on top of a GaAs wafer. The top AlAs is wet-oxidized for optical confinement in vertical direction. The finished photonic bandgap cavity is optically pumped with a 980-nm diode laser beam focused to approximately 4 mm in diameter.
