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 active layer with an AlAs layer that is wet oxidized into an Al2O3 layer subsequently. The incident threshold pump power at 0.98 μm is 9.2 mW for a ∼10-μm-diameter hexagonal cavity lasing at 1.6 μm.
