  • Abstract
    Quantum cascade distributed feedback (QC-DFB) lasers based on a heterogeneous-cascade two-wavelength active waveguide core and a multisectioned cavity featuring two different Bragg gratings are demonstrated. Optimised lasers display singlemode emission at λ~5.0 and 7.5 μm simultaneously and a tunability on both modes equal to single-wavelength QC-DFB lasers
