Polymer optical waveguide fabrication toward low insertion loss

In this work simple fabrication techniques of polymeric optical waveguides and wavegiode elements toward low insertion loss are proposed and demonstrated. For single-mode propagation, light-induced self-written (LISW) optical waveguide is fabricated. For large core optical waveguide, hot-emboss technology is adopted for the formation of platform with fiber guide. Moreover, simultaneous formation of channel waveguide with 45° mirror based on the mold technology is also reported.
