Alexander Gaeta (born 1961) is an American physicist who works on quantum and nonlinear photonics. He is currently the David M. Rickey Professor of Applied Physics at Columbia University.

Education

Gaeta received his B.S. (1983), M.S. (1985), and Ph.D. (1991) degrees in Optics from the University of Rochester. His doctoral thesis entitled, “Stochastic and Deterministic Fluctuations in Stimulated Brillouin Scattering,” was completed under the supervision of Professor Robert Boyd.

Career and research

After his postdoctoral work, Gaeta joined the faculty in the School of Applied and Engineering Physics at Cornell University in 1992. He served as its Director from 2011 to 2014 and was named the Samuel B. Eckert Professor of Engineering in 2013. He also served as the Director of the National Science Foundation Center of Nanoscale Systems in Information Technologies from 2008-2012. In 2015, he joined the Department of Applied Physics and Applied Mathematics at Columbia University where he is the David M. Rickey Professor of Applied Physics and Material Science. In 2011, he co-founded Picoluz, Inc. and in 2022 he co-founded Xscape Photonics. He was the founding Editor-in-Chief of Optica, the flagship journal of Optica (formerly the Optical Society of America).

Gaeta is known for his work in various areas of optical physics and photonics. His group performed fundamental studies on propagation of ultrashort laser pulses and slow light.[1] He also pioneered nonlinear optics in gas-filled hollow-core photonic crystal fiber, and his group also demonstrated various aspects of ultrafast optical time-lens technology including its application to temporal cloaking.[2] In collaboration with Michal Lipson’s group, his group performed many of the key demonstrations in nonlinear silicon photonics including dispersion engineering and parametric gain,[3] generation of correlated photons, Kerr comb generation in microresonators, and supercontinuum generation.

Gaeta has received numerous awards and honors including the 2019 Charles H. Townes Prize[4] from the Optical Society of America (OSA) and Fellowship from the Optical Society of America, the American Physical Society, and the Institute of Electrical and Electronic Engineers. He is also a Thomson Reuters Highly Cited Researcher.
