Abstract :
We report the first continuous-wave (CW) operation of 2D slab photonic crystal laser at room temperature. This 2D photonic bandgap laser is built on a thin InGaAsP slab waveguide structure. 2D triangular photonic crystal mirrors are formed by drilling holes. The lattice constant is 450 nm and the radius of holes is 140 nm. To locate the active layer near an anti-node of the slab, a 100nm thick layer is added on top of the active material which consists of six compressively strained (0.6%) InGaAsP quantum wells.
