Broadband distributed-feedback quantum cascade laser array operating from 8.0 to 9.8 um. IEEE Photonics Technology Letters 21(13): 914-916.1041-1135http://nrs.harvard.edu/urn-3:HUL.InstRepos:3425948An ultra-broadband distributed-feedback quantum cascade laser array was fabricated, using a heterogeneous cascade based on two bound-to-continuum designs centered at 8.4 and 9.6 mum. This array emitted in a range over 220 cm-1 near a 9-mu m wavelength, operated in pulsed mode at room temperature. The output power of the array varied between 100- and 1100-mW peak intensity.en-USJournal Article2009-12-0110.1109/LPT.2009.2020440
