About
Dan Kapsaskis is a researcher at the forefront of astrophotonics, a field that merges photonics with astronomical instrumentation. His key contributions center on the development of advanced optical coupling technologies, most notably the design of 3D free-form optical lenses that serve as miniaturised fibre couplers. This work directly addresses a critical challenge in modern multi-object spectrographs, where fibre positioning robots must efficiently capture light from numerous celestial sources across a telescope’s focal plane. By engineering compact, high-performance couplers, Kapsaskis enables more precise and efficient light transport from stars and galaxies into multi-mode fibres, enhancing the sensitivity and throughput of astronomical surveys. His most-cited paper, "3D free-form optical lens — miniaturised fibre couplers for astrophotonics" (2025), already garnering attention, showcases his innovative approach to solving practical instrumentation problems. This achievement positions him as a rising contributor to next-generation astronomical tools, with work that promises to improve how we gather light from the cosmos. His research is vital for students and researchers interested in the intersection of optics, photonics, and observational astronomy.
