Abstract
An optical communication system compensating for chromatic dispersion and a phase conjugate light generator for use therewith. The system includes an optical transmitter which receives an input signal and transmits signal light over an optical transmission line which is then input to a phase conjugate light generation unit. The phase conjugate light generation unit generates phase conjugate light corresponding to the signal light and outputs the phase conjugate light to an optical receiver which reproduces a demodulated signal corresponding to the input signal. The system compensates for chromatic dispersion by having the phase conjugate light generator generate phase conjugate light corresponding to signal light received over a first optical transmission line and then transmitting the generated phase conjugate light over a second optical transmission line.
