| Abstract | Room-temperature continuous-wave (CW) operation of distributed-feedback quantum cascade laser (DFB-QCL) emitting at 4.6 mu m is presented. Strain-compensation combined with two-phonon resonance in active region design promises low-threshold current density. A record low-threshold current density of 1 kA/cm (2) for DFB-QCL operated in CW mode at 30 degrees C is realized without a high-reflectivity coating on the rear facet. Reliable dynamic single-mode emission with a sidemode suppression ratio of about 30 dB is achieved from 10 to 50 degrees C. |
