Fabrication and characterization of polyethylene terephatate optical waveguides

Abstract

In this paper, the fabrication and characterization of polyethylene terephatate (PET) thin film integrated opti- cal waveguide is presented. Dip-coating technique has been used to fabricate the optical waveguide using PET. Various waveguide properties, such as mode effective refractive in- dex, optical loss, dispersion and waveguide thickness as a function of temperature of waveguides have been reported. The optical loss are found to be < 1d B cm � 1 .
