Seminar 3/13/2013 - John Ballato, Clemson University: Extraordinary Optical Fibers from Otherwise Boring Materials
Abstract: Optical fibers have become ubiquitous due to the remarkable properties of silica which enables, among other things, high strength and low transmission losses. But despite its 40 year reign silica is showing chinks in its armor as new applications place heavier demands on performance. This talk will focus on a new class of optical fibers based on materials that are so well accepted (just not as fibers) as to be considered boring. Particular attention will be paid to novel optical fibers derived from silicon, germanium, YAG, and sapphire. Their extraordinary properties will be discussed including nonlinearities which are very strong in some cases and exceedingly weak in others and applications that will benefit from their unusual performance.
Bio: Dr. John Ballato is a professor of materials science and engineering (MSE) and electrical and computer engineering (ECE) at Clemson University where he also directs the Center for Optical Materials Science and Engineering Technologies (COMSET). Previously, Dr. Ballato served as Clemson's Associate Vice President for Research and Economic Development and as interim Vice President for Research. He earned a B.S. in Ceramic Science and Engineering (1993) and the Ph.D. in Ceramic and Materials Engineering (1997) from Rutgers, The State University of New Jersey. Dr. Ballato has published more than 200 archival scientific papers, holds 25 U.S. and foreign patents, has given in excess of 125 invited lectures/colloquia, and has co-organized 25 national and international conferences and symposia. Among other honors, he is a Fellow of the Optical Society of America (OSA), the International Society of Optical Engineering (SPIE), and the American Ceramic Society (ACerS). He has been a Principal Investigator on more than $40 million worth of sponsored programs, gifts and contracts. He is an Associate Editor of the Journal of the American Ceramic Society, Topical Editor for Optics Letters and is an active participant on the "Optoelectronic Glasses" technical committee for the International Commission on Glass (ICG).
All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.
