Abstract: The optical properties of solid samples of polymethyl-methacrylate doped with fulgide photochromic molecules were studied. The transmittance of a thin plate sample was measured when both the activation (UV) and bleaching wavelengths are employed. The samples were used as an optical switch where an UV pulse switches a visible signal beam. The behaviour of these compounds as holographic materials, studied by efficiency measurements at varying grating steps, is reported. We realised the experimental set-up for the measurements in competition with simultaneous UV and visible irradiation on the photochromic sample. The results are the transmittance of the fulgide 611TD in polymethil-methacrylate measured for increasing value of the input visible light, the test were performed for different levels of the UV irradiation on the sample.
