Abstract
Quantum cascade lasers are new intersubband light sources in which the wavelength can be tailored over a broad range of the infrared spectru m using the same heterostructure material by changing the active layer thickness. Room temperature operation at 5 and 8.5 mu m has been achi eved. These are the first semiconductor lasers to operate at 300K and above in this wavelength region.
