This Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) provides $450,000 over 3 years to Virginia Polytechnic Institute & State University (Virginia Tech) to conduct research on developing tunable wavelength GeSn lasers and mid-wavelength infrared (MWIR) photodetectors on lattice-matched InAl(Ga)As buffers for Group IV photonics. The research aims to advance technologies supporting the CHIPS and Science Act of 2022 and quantum technology development. Key areas of investigation include: (1) synthesizing low-defect, tunable GeSn materials on lattice-matched InAl(Ga)As buffers; (2) increasing band offsets and carrier confinement in GeSn quantum wells for improved laser performance; (3) designing and simulating GeSn/InAl(Ga)As quantum well laser and MWIR photodetector architectures; (4) fabricating and demonstrating GeSn quantum well lasers and photodetectors. This research is expected to establish pathways for high-performance Group IV lasers and detectors with applications in communications, biomedical, and defense systems. The award will also provide research experience for undergraduate and graduate students in photonics.
