Optical characteristics of a dye-doped (polymer/liquid crystal) composite film do not depends much on wavelength and polarization. Such a film is expected to be applied to a variable optical attenuator. To clarify extinction mechanism of the film, we evaluated its scattering intensity dependencies on the wavelength and scattering angle. Some experimental data have been obtained, which suggest scattering is a primary mechanism of the extinction.
