Summary: | The embodiment of the invention discloses a stable decoy state pulse intensity modulation method and an intensity modulator, and the method comprises the steps: under the condition that the intensity of the decoy state pulse output by the intensity modulator is a stable point, determining the number of channels of an intensity modulator, the beam splitting ratio of a beam splitter in each channel, the attenuation rate of an adjustable attenuator and the target input pulse intensity of the input intensity modulator; through the maximum decoy state pulse intensity,determining target direct current voltage intensity needing to be loaded by each first terminal; and under the condition that the first terminal loads the target direct-current voltage intensity and the input pulse intensity is the target input pulse intensity, determining radio-frequency signal amplitudes needing to be loaded by the second terminals corresponding to decoy state pulses with different intensities through a preset first formula; therefo |
