Affordable and Efficient High-Power Long Wavelength Infrared Quantum Cascade Lasers

Pendar Technologies proposes to develop the next generation of compact, high power long-wave infrared (LWIR) quantum cascade laser (QCL) sources with output power and wall-plug efficiency exceeding 4 Watts and 16 percent respectively. Innovations such as new low-loss waveguides and novel bandstructure capable of improving the performance of the laser emitters over the state-of-the-art will be implemented. New production methods and QCL designs that enables the efficient manufacturing of our optical source with high yield, batch-to-batch repeatability and low-cost, wafer-scale testing will also be developed. The goal is to demonstrate that LWIR high power QCLs can both have significantly better overall performance and also be more affordable at the same time.
