Influence of Phase Constant Difference between Dispersive Elements in Difference-Frequency Generation Based Optical-Phase-Conjugation Circuit

Influence of phase constant difference between two dispersive elements in difference-frequency generation based opticalphase-conjugator is theoretically studied. Calculation results show a slight change of a phase constant due to refractive index change with 1.0 × 10-7order severely affects output phase-conjugated signal power.
