Mode confinement of light wave propagation in a new polymeric waveguide studied by the m-lines technique

摘要

Transmission properties of a novel optical waveguide structure based on Nafion polymer are investigated by the technique of the m-line spectroscopy at a wavelength of 632.8 nm. The refractive index profiles for Nafion film for both TE and TM modes are found to be of quadratic nature with surface refractive indices values of 1.3408 and 1.3446 respectively. The attenuation loss of this polymeric waveguide is found to be 1.53 dBcm~(-1).
