Embodiment Construction
[0018] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0019] This embodiment provides a transmitting end of a reflective coherent optical communication system, and its structural schematic diagram is as follows figure 1 As shown, including polarization controller, polarization beam splitter, polarization maintaining circulator, reflective modulator, polarization maintaining coupler, photoelectric converter and electrical comparator;
[0020] After the optical carrier transmitted by the receiving end is transmitted through space, it passes through the polarization controller to output an optical carrier with a polarization state, and then splits it into two optical carriers whose polarization states are perpendicular to each other through a polarization beam splitter; the first optical carrier is coupled through polarization maintaining Two beams of light with different powers are obtained after the device;...
