Measuring anisotropic refractive indices and film thicknesses of thin organic crystals using the prism coupling method.
Anisotropic refractive indices of the organic biaxial thin-film crystal, 2-methyl-4-nitroaniline (MNA), were determined by the prism coupling method. The experiment was carried out on an anisotropic waveguide of the MNA monocrystal film by an incorporated analysis of the TE and TM waves.
