Porous Polyethylene Terephthalate Optical Waveguide for Sensing Applications

We report the fabrication and characterization of optical waveguides using porous polyethylene terephthalate (PET) film. An optical waveguide is produced by exposing the PET film to cyclotron followed by selective chemical etching. Considering that the average refractive index of porous regions is l...
