John Sitch was born in London and educated at Oxford and Sheffield. During his career in industry and academe he has worked mostly with RF, microwave and optical semiconductor devices. Since 2003 he has semiconductor devices. Since 2003 he has worked in optical systems with Nortel and now Ciena. The recipient of a 1996 R&D 100 award, Dr. Sitch was Chairperson of the 2001 IEEE GaAs IC Symposium. John Sitch Senior Advisor, Digital/Optical Systems Email: jsitch@ciena.com Tel: (+1) 613 763 3851
