Robert Alfano received the 2019 SPIE Gold Medal, the highest honor bestowed by the society, during the awards banquet at the SPIE Optics + Photonics conference this month.

Alfano, professor of science and engineering at The City College of New York and a member of the Photonics Media advisory board, was recognized for his numerous achievements and contributions to the advancement of knowledge on the fundamental properties of materials and their interaction with light in areas of biology, condensed matter, semiconductors, tunable lasers, and biomedical optics.

Among Alfano’s most notable achievements is the discovery and subsequent development of supercontinuum light produced with an ultrashort pulsed laser. He also contributed to the field of biophotonics in the 1980s and 1990s, yielding techniques for optical biopsy. Alfano’s work on time-gated diffusive light propagation in tissue during the same time period also helped develop the fields of near-infrared spectroscopy and imaging in random media.

“Alfano is, and has long been, one of the most widely respected and influential figures in laser physics,” said David Andrews, professor of physics at University of East Anglia and SPIE vice president.

Most recently, Alfano has studied structured light, another field he has made important contributions in, including the theoretical construction of a new Poincaré sphere for the total angular momentum of light. Andrew Forbes, professor of physics at University of the Witwatersand, Johannesburg, commented, “It is no small feat to reinvent a concept so ubiquitous in optics.”
