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

TransWave Photonics, LLC in collaboration with the University of Texas at Austin 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 1 work, the proposing team will perform theoretical investigations and preliminary experimental demonstrations of the key innovations to demonstrate the technical feasibility of the proposed approach.
