William Streifer Scientific Achievement Award

The IEEE Photonics Society William Streifer Scientific Achievement Award is given to recognize an exceptional single scientific contribution which has had a significant impact in the field of lasers and electro-optics in the past 10 years. It may be given to an individual or to a group for a single contribution of significant work in the field. The Award is endowed by Xerox Corp and Spectra Diode Labs. The Award consists of an honorarium of $2,500 and a medal. The presentation is made at the IEEE Photonics Conference.

Please note that no candidate shall have previously received a major IEEE award for the same work.  Previous winners of a Photonics Society Career Award (Aron Kressel, Engineering Achievement, Quantum Electronics, William Streifer Scientific Achievement) are not eligible candidates for consideration of the same work. Candidates need not be members of the IEEE or the Photonics Society. 

2020 Honoree

Delfyett 20161104Peter J. Delfyett, Jr.

For pioneering contributions to semiconductor diode based ultrafast laser science and technology.





Peter Delfyett received the B.E.(E.E.) degree from The City College of New York, the M.S. degree in EE from The University of Rochester, the M. Phil and Ph.D. degrees from The Graduate School & University Center of the City University of New York.  After obtaining the Ph.D. degree, he joined Bell Communication Research as a Member of the Technical Staff, where he concentrated his efforts towards generating ultrafast high power optical pulses from semiconductor diode lasers, for applications in applied photonic networks.


In 1993, he moved to University of Central Florida, where he is Pegasus Professor and Trustee Chair Professor of Optics, EE & Physics in CREOL, The College of Optics and Photonics, and is currently serving as the Director of the Townes Laser Institute.


He is a Fellow of the APS, IEEE, NAI, NSBP, OSA, and SPIE.  He is also the recipient of the NSF PECASE Award, the APS Edward Bouchet Award, the 2014 Medalist from the Florida Academy of Science, and the 2018 Townsend Harris Award.  He has over 750 scientific publications in refereed journals and conference proceedings and 43 US patents.
