Abstract
This paper reports the realization of a long-wavelength quantum cascade laser employing so-called 'chirped' superlattices and operating at λ approx. 17 μm. This represents the first demonstration of a semiconductor injection laser based on intra-band transitions at wavelengths beyond the atmospheric windows. The structure was grown by molecular beam epitaxy in the InGaAs/InAlAs material system lattice matched to InP substrate.
