Abstract

A monolithic tunable mid-infrared laser has a wavelength range within the range of 3-14 μm and comprises a heterogeneous quantum cascade active region together with at least a first integrated grating. The heterogeneous quantum cascade active region comprises at least one stack, the stack comprising two, desirably at least three differing stages. Methods of operating and calibrating the laser are also disclosed.
