Abstract :
To clarify extinction mechanism of a dye-doped (polymer/liquid crystal) composite film variable optical attenuator, we evaluated its scattering intensity dependencies on the wavelength and scattering angle. We have obtained some experimental data that suggest Rayleigh scattering is a primary mechanism of extinction.
