Semiconductor Optical Amplifiers
Dr A E Kelly has worked on Semiconductor Optical Amplifiers since 1993 and has used them in a range of applications including the demonstration of the worlds fastest regenerative logic gate in 1999. He has produced a number of devices with world record performance and still holds the record for the lowest fibre to fibre SOA noise figure. This work was commercialised through Kamelian Ltd and Amphotonix Ltd. He currently has interests in their use for next generation PON systems.
