摘要： A broadband quantum cascade laser includes multiple gain regions and a spacer layer disposed between at least two of the gain regions. The arrangement and characteristics of the gain regions and the spacer layer may be configured to reduce cross absorption between the gain regions. For example, one gain region may be configured to produce gain in an energy range in which another gain region produces absorptive effects. The thickness of the spacer layer may be selected to separate optical modes produced by adjacent gain regions while still producing a single broadband output from the quantum cascade laser. Gain competition between gain stages within a gain region may be mitigated by dividing gain stages with overlapping gain curves among multiple gain regions.

摘要： A broadband quantum cascade laser (QCL) source includes one or more QCLs having an active region designed based on a diagonal laser transition. The QCL source may include multiple QCLs formed in an array or the QCL source may comprise a single QCL device. Although each QCL provides an emission spectrum comprising a small range of wavelengths at a given applied voltage, changes in the applied operating voltage result in changes in the emission spectrum of the QCL due to the Stark shift. When the QCL source comprises a plurality of QCLs formed in an array, at least some of the elements in the array may receive different applied operating voltages such that the combined output spectrum of the array is broader than that achievable by a single QCL. When the QCL source comprises a single QCL device, an applied operating voltage may be swept through a range of applied voltages such that that combined output spectrum over one sweep cycle is broader than the output spectrum of the QCL device when a static operating voltage is applied. Alternatively, the single QCL device may comprise multiple independent gain sections, wherein each of the independent gain sections is configured to operate at a different voltages to provide a broadband output spectrum.
