Abstract
Monolithic, wavelength-tunable QCL devices are provided which comprise a substrate, an array of QCLs formed on the substrate and an optical beam combiner formed on the substrate electrically isolated from the array of QCLs. In embodiments, the QCL devices are configured to provide laser emission in the range of from about 3 μm to about 12 μm, a wavelength tuning range of at least about 500 cm, and a wavelength tuning step size of about 1.0 nm or less.
