A quantum cascade (QC) laser employing chirped superlattices and operating at λ to approximately 17 μm, which represents the first demonstration of a semiconductor injection laser based on intra-band transitions at wavelengths beyond the atmosphere windows, is fabricated. A schematic band diagram of the structure, grown by MBE in InGaAs/InAlAs material system lattice matched to InP substrate, is presented.
