Mid-infrared quantum cascade lasers with highly efficient heat extraction architecture

TransWave Photonics, LLC proposes to demonstrate a new active region and thermal packaging configuration for the mid-wave infrared quantum cascade lasers that provide both high modal overlap with the laser active region and a dramatically reduced thermal impedance of the laser compared to the current state-of-the-art. The proposed laser design concept allows for scaling of continuous-wave power output from mid-wave infrared quantum cascade lasers beyond the current state-of-the-art. In Phase II, the proposing team will demonstrate a single QCL device producing > 5 W room temperature continuous wave optical power with diffraction limited beam by improving thermal impedance of the device by a factor of two.
