Abstract
The University of Central Florida invention is an optimized mid-infrared quantum cascade laser (QCL) design capable of delivering multi-watt continuous wave (CW) power in a high-quality output beam. The design comprises InP spacers whose thickness, as well as other design parameters, is adjusted to simultaneously achieve a high CW power and high beam quality. The design method uses a semi-empirical model to predict CW performance for a QCL configuration can serve as a critical tool for the QCL performance optimization without the need to fabricate and test each proposed device. Applications include infrared countermeasures, infrared beacons and target designators, infrared illumination, hyperspectral imaging, plasmonics, and metamaterials.
