Abstract
Room temperature operation of lasing from optically-pumped InAs quantum dots embedded in a line defect waveguide in a two-dimensional air-bridge type GaAs-photonic crystal slab is demonstrated. The lasing is found to occur without Fabry-Perot mirrors, and also without any reflection at the sample edge. A distributed feedback mechanism at the band edge with a vanishingly-small group-velocity is responsible for the present lasing.
