| Résumé |
Continuous-wave operation of lambdasimilar to9 mum
distributed-feedback quantum-cascade lasers is reported up to a
temperature of 260 K. Single-frequency emission with a side mode
suppression ratio of greater than or equal to27 dB and with a
tuning range of 5 cm(-1) between 200 and 245 K (a tunability of
-0.078 cm(-1)/K and -0.764 cm(-1)/W) is obtained for the
junction-down mounted buried heterostructure devices. Uncoated
lasers display an output power of up to 18 mW at 180 K and still 1
mW at 250 K. Lasers with high-reflection coated facets could be
operated up to 260 K. (C) 2003 American Institute of Physics. |
