摘　　要：Pattern formation in azobenzene polymer film by degenerate four-wave mixing is reported.Island arrays with specific patterns are analyzed with scanning electron microscopy and polarizing optical microscopy.It is demonstrated that the control of photo-induced nanostructure sized micropattern in the nonlinear organic film is possible by using properly polarized writing beams with the total incident power exceeding a certain threshold.
