摘要: Using nonlinear photoinduced anisotropy in bacteriorhodopsin (bR) film, we presented and demonstrated an image switch in which the output can be tuned continuously by the intensity of a pumping beam. A laser with wavelength 532 nm was used as the pumping beam, and a He-Ne laser at wavelength 632.8 nm was used as the probe beam. Without pumping light, a little of polarized probe beam can transmit the crossed polarizers and the output is very low. With the presence of pumping light, owing to photoinduced anisotropy in the bR film, a portion of the probe beam transmits the crossed polarizers, depending on the intensity of the pumping beam. For the low-intensity probe beam (0.44 mW/cm(2)), the output is dependent on a wide range of pumping beam (2-30 mW/cm(2)). On the contrary, for the high-intensity probe beam (0.80 mW/cm(2)), the output is dependent on a narrow range of pumping beam (2-7 mW/cm(2)). (C) 2008 Elsevier GmbH. All rights reserved.
