Abstract
Summary form only given. Quantum cascade (QC) lasers are unipolar semiconductor lasers emitting in the midinfrared wavelength range. As these devices are based on intersubband transitions the emitted wavelength is essentially determined by quantum confinement. We present a new process for buried heterostructure QC lasers with improved waveguiding and better heat dissipation compared to conventional QC lasers.
