Abstract

Spatial light modulation by use of a biphotonic holographic grating has been demonstrated in an azobenzene-doped polymer film. The mechanism of incoherent-to-coherent optical conversion originates from the photoinduced trans↔cis isomerization of azobenzene molecules by two color lights. It is also found that when the intensity of the blue beam is varied the output replica of the input information changes sign.
