Peter Delfyett

Peter J. Delfyett Jr (born March 8, 1959) is an American engineer and Pegasus Professor and Trustee Chair Professor of Optics, ECE & Physics at the University of Central Florida College of Optics and Photonics.

He was awarded the 1996 Presidential Early Career Award for Scientists and Engineers.

He is a Fellow of the American Physical Society and The Optical Society. Delfyett was also elected a member of the National Academy of Engineering in 2021 for contributions to development and commercialization of low-noise, high-power ultrafast semiconductor lasers.

Early life and education Delfyett, who is African-American, was born in Queens, New York. When he was in his first grade he was taken to see the film Journey to the Beginning of Time. He attended the City College of New York, where he studied electrical engineering. Whilst he was a sophomore Delfyett became interested in optics. He was mentored by Robert Alfano. His doctoral research focussed on ultrafast spectroscopy. After graduating, Delfyett joined Bell Communication Research (now Iconectiv) where he worked on semiconductor lasers. At Bellcore, Delfyett created the highest power mode-locked diode laser in the world.

Research and career In 1993 Delfyett moved to the University of Central Florida College of Optics and Photonics (CREOL), where he was made the Professor of Optics and Photonics. Here he established an Ultrafast Photonics group who worked on semiconductor lasers. He developed the semiconductor laser diode that could achieve the shortest and most intense laser pulse in the world.
