Abstract
Wideband, highly noise-suppressed squeezing was observed by using a high-sp eed, high-quantum-efficiency light-emitting diode. The squeezing bandwidth extended over 200 MHz. We also have investigated the dependence of the sque ezing bandwidth on the pump-current at low temperature. The experimental re sult was compared with the theoretical predictions based on a unified model of the pump and recombination process and was well explained by the model at the thermionic emission limit.
