About
Sarath D. Gunapala is a pioneering figure in infrared detector technology, best known for his groundbreaking work on Quantum Well Infrared Photodetectors (QWIPs) and strained-layer superlattices (SLS). His research has fundamentally advanced the development of large-format, high-performance focal plane arrays for space-based and terrestrial imaging. Gunapala’s major contributions include leading the effort at NASA’s Jet Propulsion Laboratory to transition QWIPs from single-element devices to megapixel two-dimensional arrays, enabling their use in Earth observation, astronomy, and defense. His work on the Landsat program and the International Space Station has directly supported critical climate and environmental monitoring missions. With over 5,000 citations, his papers on QWIP design, material optimization, and system integration are foundational references in the field. Notably, his 2020 paper on “QWIPs, SLS, Landsat and the International Space Station” highlights the enduring impact of his innovations on space-based remote sensing. Gunapala’s achievements include multiple NASA awards and the prestigious IEEE Simon Ramo Medal, reflecting his transformative role in infrared photonics and sensor technology.
