Physics-Based Laser Device Modeling

ACT is developing physics based models to predict the behavior of mid-IR bismide doped lasers, based on rigorous understanding of “atom-up” physics. The fundamental insights gained in this work and the resulting model will provide a quantitative simulation capability for understanding the gain/loss behavior of laser structures producing Watt level output at 3-5 microns. The tool will also enable improvements to design process of future quantum cascade laser (QCL), which will be beneficial to commercial applications in area of telecommunications, chemical effluent sensing and medical diagnostics.
