Paper Abstract

Polyimide-polymer coated silver hollow glass-waveguides have been proposed for the first time as infrared light transmitting media for the applications in the fields of medicine and infrared sensors. The waveguides with inner diameter of 0.7 mm and length of 1 m have been fabricated by inner coating of polyimide and silver inside a fused- silica capillary tube. By measurements of the loss spectra of the waveguides, it is shown that polyimide-polymer coated silver hollow glass-waveguides have low-loss characteristics at some infrared wavelength regions. As a dielectric material, the polyimide-polymer has many advantages such as high heat-resistance, nontoxicity, durability, and low refractive index over other dielectrics. Moreover, a fabrication method employing liquid-flow coating leads to a possibility of the mass- production of the waveguides.
