摘要：

This paper describes the generation and observation of sub-Poissonian light in an open-loop system with low quantum efficiency at room temperature. The experimental results show that the photocurrent fluctuation spectrum density can be reduced below the shot noise limit by 72% (-5.5 dB) in an open-loop light-emitting diode (LED) system at the frequency of 2 MHz. The noise reduction is not limited by quantum efficiency of the LED, or the current transfer efficiency.
