Abstract
UV-Writing Poly(FPS-co-GMA) for optical waveguide was synthesized and the refractive index of the polymer film was tuned in the range of 1.460~1.555 at 1550 nm by mixing with bis-phenol-A epoxy resin. The film, which was made by spinning coated the Poly(FPS-co-GMA) with photo initiator, had good UV light lithograph sensitivity. The optical waveguides with very smooth top surface were fabricated from the resulting polymer by direct UV exposure and chemical development. The propagation losses of the channel waveguides were measured to be below 0.6 dB/cm at 1550 nm.
