Jeremy Allam

Professor of Ultrafast Optoelectronics



Jeremy Allam obtained his first degree in Physics from the University of Oxford, and his PhD from Surrey. After working for 2 years at AT&T Bell Laboratories and for 3 years as a postdoc sponsored by British Telecom, in 1990 he joined the newly-formed Hitachi Cambridge Laboratory where he formed a group working in Femtosecond Optoelectronics. In April 2000 he was appointed to a Chair in Ultrafast Optoelectronics.

Research interests

Jeremy's research interests include ultrafast carrier dynamics in semiconductors for optoelectronic devices, high-speed photonic measurement technologies, and high-field carrier transport. He has recently commissioned a a new ultrafast laser facility comprising laser oscillators and amplifiers, parametric oscillators and amplifiers, and frequency mixers, providing a capability for <100 fs optical pulses from UV to the mid-IR wavelengths.
