| 英文摘要 | a new coherent laser communication detection scheme based on the channel-switching method is proposed. the detection front end of this scheme comprises a 90 degrees optical hybrid and two balanced photodetectors which outputs the in-phase (i) channel and quadrature-phase (q) channel signal current, respectively. with this method, the ultrahigh speed analog/digital transform of the signal of the i or q channel is not required. the phase error between the signal and local lasers is obtained by simple analog circuit. using the phase error signal, the signals of the i/q channel are switched alternately. the principle of this detection scheme is presented. moreover, the comparison of the sensitivity of this scheme with that of homodyne detection with an optical phase-locked loop is discussed. an experimental setup was constructed to verify the proposed detection scheme. the offline processing procedure and results are presented. this scheme could be realized through simple structure and has potential applications in cost-effective high-speed laser communication.
