| 英文摘要 | 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. |
