High performance index-coupled quantum cascade distributed feedback (QC-DFB) lasers operating at lambda approximate to 8.5 mu m are reported. Reliable dynamic single-mode emission with a side mode suppression ratio greater than or equal to 30 dB is obtained. The continuous single-mode tuning range is 140 nm. In pulsed operation a record high peak output power of 60 mW at 300 K is achieved. We further report on the first continuous-wave QC-DFB lasers. These devices display an output power of 10 mW at 120 K.

Abstract
High performance index-coupled quantum cascade distributed feedback (QC-DFB) lasers operating at lambda approximate to 8.5 mu m are reported. Reliable dynamic single-mode emission with a side mode suppression ratio greater than or equal to 30 dB is obtained. The continuous single-mode tuning range is 140 nm. In pulsed operation a record high peak output power of 60 mW at 300 K is achieved. We further report on the first continuous-wave QC-DFB lasers. These devices display an output power of 10 mW at 120 K.File in questo prodotto:
