| Abstract: | The simulation of laser communications with electrooptics modulation is realized in laboratory. The theory of electrooptics modulation is discussed and the effects of crystal＂ s electrooptics modulation characteristic on the quality of communication are analyzed by comparing the modulated signal with the demodulated signal that are collected in experiment. Then it is found that the tune position of modulated signal and the modulated signal amplitude are important factors to effect the quality of communication. |
