Abstract :
A new type of low-noise optoelectronic amplifier is proposed which uses intensity-squeezed light from a tandem array of high quantum efficiency laser diodes or light-emitting diodes. Applications include amplification of intensity-squeezed light, sub-shot noise modulated lightwave generation for free-space and fibre transmission, and low noise small signal RF amplification.
