Biography

In 1981 he worked at StorageTek of Louisville, CO, in the area of optical data storage. In 1986, he worked at Columbia University in the areas of photonic switching systems and ultra-fast all-optical networks and signal processing. From 1993 to 1997 he was Assistant Professor in the School of Electrical and Computer Engineering at the Georgia Institute of Technology. He is currently the Associate Director for the Center on Multidisciplinary Optical Switching Technology (MOST) and Professor in the Department of Electrical and Computer Engineering at the University of California - Santa Barbara. Dr. Blumenthal heads the Optical Communications and Photonic Networks (OCPN) Research. Dr. Blumenthal is Co-Founder of Calient Networks, a manufacturer of photonic switching systems based in San Jose, CA. His current research areas are in optical communications, photonic packet switched and all-optical networks, all-optical wavelength conversion, photonic integration and nanophotonics. He has authored or co-authored over 100 papers in these and related areas. Dr. Blumenthal is recipient of a 1999 Presidential Early Carreer Award for Scientists and Engineers (PECASE), a 1994 NSF Young Investigator (NYI) Award and a 1997 Office of Naval Research Young Investigator Program (YIP) Award. He has serverd as an Associate Editor for IEEE Photonics Technology Letters and for the IEEE Transactions on Communications. He was a Guest Editor for the IEEE Journal of Lightwave Technology Special Issue in Photonic Packet Switching Systems, Technologies and Techniques published in December, 1998 and is currently a Guest Editor for the IEEE JSAC Special Issue on High-Performance Optical/Electronic Switches/Routers for High-Speed Internet. He also served as General Chair and Program Chair for the OSA 1999 and 2000 Topical Meetings on Photonics in Switching respectively and has served on numerous conference committees including the technical program committees for the Conference on Optical Fiber Communications (OFC) in 1997, 1998, 1999 and 2000 and the Conference on Lasers and Electrooptics (CLEO) in 1999, 2000 and 2001. He is a Fellow of IEEE, and a member of the Optical Society of America and the Lasers and Electrooptic Society.
