Abstract :
In this paper InAs/AlSb quantum cascade structures operating at room temperature with peak emission wavelength down to 2.55 μm, the shortest emission wavelength of intersubband transitions reported to date. No degradation in structure performances was observed with the emission wavelength decreasing from 4.5 to 2.55 μm. The obtained results prove the great potential of the InAs/AlSb system for the development of short wavelength QCLs.
