Continuous room-temperature operation of optically pumped two-dimensional photonic crystal lasers at 1.6 μm

In this letter continuous operation is realized from two-dimensional slab photonic crystal lasers at room temperature. The laser structure is prepared by wafer fusion of an InGaAsP MQW active layer with an AlAs layer that is wet oxidized into an Al 2 O 3 layer subsequently. The incident threshold pu...

Summary:In this letter continuous operation is realized from two-dimensional slab photonic crystal lasers at room temperature. The laser structure is prepared by wafer fusion of an InGaAsP MQW active layer with an AlAs layer that is wet oxidized into an Al 2 O 3 layer subsequently. The incident threshold pump power at 0.98 μm is 9.2 mW for a /spl sim/10-μm-diameter hexagonal cavity lasing at 1.6 μm.
