Abstract

Recently there has been much interest in non-classical light both in theoretical and experimental study. The scheme utilizing semiconductor devices is especially attractive because of its simple experimental configuration and small energy consumption.^1,2 From a practical view-point, it is important to generate weak sub-Poissonian light.³ Light emitting diodes (LED) have the advantage of generating weak sub-Poissonian light over laser diodes because LEDs have much higher emission efficiency when the input current is low.
