“…A holographic recording at a wavelength of 514.5 nm with diffraction efficiency 8% in a polymer film doped with compound C in figure 2 was reported earlier by us [8] and also, to the best of our knowledge, we have observed a highest value of nonlinear refractive index of 1.7 × 10 −6 cm −2 W −1 from compound-B-doped PMMA film [9]. However, generally, comparing with the spectrum made in dilute solution or in thin film, as the thickness of film samples increase, the sideband of their absorption curve will extend towards longer wavelength rapidly.…”

“…Their refractive index and absorption variation or mass transport will arise from the photoinduced changes in the isomer populations [5]. As it is indicated that when two writing light beams with same polarization or with mutually orthogonal polarization interfere in such system, the interference pattern of the recording light will spatially modulate the photoinduced changes in the isomer populations or spatially modulate the molecular orientational distribution, resulting in the phase or amplitude grating, or resulting in polarization holographic grating in the film [8]. However, in order to distinguish the formation mechanisms of the two gratings, more research work is needed.…”
