TransWave Photonics, LLC SBIR Phase I Award, October 2020

TransWave Photonics proposes to develop a monolithic, mass-producible quantum cascade laser emitting at two mid-wave infrared bands. Leveraging expertise in development of high power dual-wavelength mid-infrared quantum cascade lasers, we propose a heterogeneous active region capable to produce continuous-wave output power more than 3W for each band and wall-plug efficiency higher than 15% at room temperature. The proposed device will emit a nearly diffraction-limited laser beam from a single aperture without using any free-space optics or moving parts.
