- Abstract
- Tuning of the emission wavelength in GaAs/AlxGa1-xAs bound-to-continuum quantum cascade lasers with different Al mole fractions (x) is reported. By varying x in the range of 0.37-0.52, a shift of the emission wavelengths of over 4 mu m has been observed. Using this method, laser action in the range of 11.2-15.3 mu m at temperatures T >= 260 K has been demonstrated with a record value of similar to 340 K for GaAs based QCLs operating at 13.5 mu m.
