Paper Abstract

Light-sensitive liquid films are used to produce cross-modulation between light beams in an all-optical device. In the first setup presented in this paper a laser beam (HeNe, CK, 1 mW) is switched-on (off) when another laser beam (HeNe, ON, 10 mW) is switched-off (on). The diameter of the interaction region in the liquid film is about lmm. In another setup, large-scale deformations of the liquid film (diameter about Smm.) are induced by heating with a white-light source. The deformed region behaves as a mirror whose radius depends on the intensity of the heating beam.
