摘要

Degenerate four-wave mixing phase conjugation is observed in azo-dye-doped polymer optical fibers under low-power, continuous-wave laser irradiation. A maximum phase conjugate efficiency of 1% has been obtained under a power less than 3 mW for each beam inside the fiber. Phase conjugation is observed for both parallel- and orthogonally-polarized probe and pump beams. The polarization and intensity profile are verified to be preserved in the conjugate signal. The predominant phase conjugation signal is attributed to photoinduced isomerization and reorientation of azo-dye molecules.
