WebRIN(dB/Hz)為雷射的相對強度雜訊(Relative Intensity Noise;RIN)。 由(3.7)式中可以得知,載波雜訊比值會受到接收機的熱雜訊、散彈雜訊 以及雷射的相對強度雜訊所影響。另 … Webdamental intensity noise floor of semiconductor laser light can be re- duced over a wide bandwidth by the ratio 1/( 1 + o*), where 01 is the linewidth enhancement factor. The method uses a dispersive element to convert phase noise into intensity noise. We recently demonstrated this technique by reducing intensity noise from a DFB laser as much
