摘要

Transient optical modulation properties of a disperse-red-1-doped polymer film are investigated by use of four-wave mixing with two-color light. Interesting behavior is observed for the transient modulation on variation of the two-color light intensities because of competition between the two mechanisms of one-photon (reorientation) and biphoton (isomerization) gratings. Positive and negative modulation as well as double-frequency modulation relative to blue-light input is observed in the experiment. The results may have applications in optical information processing.
