Coherent Optical Communication,ately 20 dB (homodyne detection can reach 23 dB), allowing for longer distance transmission under the same power. Furthermore, coherent optical communication systems are more conductive to the suppression of atmospheric turbulence and channel fading. This chapter introduces the concepts behind coherent optical communication.

Wavefont Correction Technique of Spatial Coherent Optical Communication with LC-SLM,ht modulator (LC-SLM-R) is explained and experiments on the phase modulation characteristics of beams of various wavelengths incident on the LC-SLM are discussed. After calibration, the phase–grayscale relationship diagrams of the LC-SLM under various wavelengths are presented, and the feasibility o
