Continuous wave operation of gimel similar to 19 mu m surface-plasmon quantum cascade lasers
02 August 2001
Continuous wave laser action has been achieved in a superlattice quantum cascade device operating on surface plasmon waveguide modes. The emission wavelength lambda - 19 mum is by far the longest ever reported for continuous wave III-V semiconductor lasers. The output power at cryogenic temperature is of the order of the mW.
