Paper Abstract

Interband cascade lasers are efficient and compact semiconductor mid-infrared (3-6 μm) light sources with low-power consumptions. We report our recent progress in the development of interband cascade lasers with separate confinement layers. Broad-area (0.1mmx1mm) lasers have been operated in cw mode at temperatures up to 213K near 3.36 μm. For narrow ridge-waveguide (0.01mmx1.5mm) lasers, cw operation has been achieved at temperatures up to 266K near 3.43 μm, 260K near 3.7 μm, and 238K near 4.04 μm. The results on both broad-area and narrow-ridge IC lasers are discussed in comparison with previous regular IC lasers without separate confinement layers.
