TransWave Photonics, LLC SBIR Phase I Award, June 2020

TransWave Photonics proposes a photonic integration architecture for efficient coherent beam combining of quantum cascade arrays consisting of more than 10 elements to generate > 10 W continuous-wave output power with 90% combining efficiency at room temperature. The proposed beam combiner will produce diffraction-limited laser beam with at least one order of magnitude higher brightness than the state-of-the-art quantum cascade laser beam combiners. In addition, our integration platform allows for seamless integration of a monolithic modulator for high-speed laser intensity modulation.
