- Abstract
- We have studied the electro-optical and angular behavior of holographic-polymer-dispersed liquid crystal
gratings at different wavelengths, in the visible and in the near-infrared range. As usual in these kinds of
materials, a strong polarization dependent behavior was observed. Our samples showed very high diffraction
efficiency for p-polarized radiation at 1.55 ?m, which is very interesting for many possible applications in the
telecom field. However, we also observed a very unusual behavior for visible p-polarized light and we try to
suggest some explanation for that. By analyzing the angular dependence of the diffraction efficiency, we could
measure the components of the permittivity modulation tensor and infer important information about the main
parameters involved in the grating structure: the degree of phase separation and the anisotropy in the liquid
crystal droplet distribution. In our opinion, this simple and nondestructive methodology can be very useful for
studying these kinds of materials and getting information on their morphology, in view of optimizing their
properties. Finally, we discuss the role of the refractive index optical dispersion in order to describe the
behavior of these materials at different wavelengths. These remarks are especially important when properties in
the infrared range are extrapolated from measurements in the visible. (literal)
