Abstract
Brillouin component is observed for the first time along the backscattered m lines in the anisotropic film waveguides. Each order of the forward as well as the backscattered m lines is found to be split into two components and are attributed to the presence of TE and TM modes. Temperature conditions under which the films are made and the thickness of the films are found to be critical. Polystyrene films are used in the investigations as waveguide materials due to their compatibility.
