Fabrication of low-loss polymeric optical waveguide for multi-mode and polymer optical fibers based on hot-emboss technique

摘要

Simple and low cost fabrication of method polymeric optical waveguides with large core sizes for multi-mode fibers and polymer optical fibers (POFs) is presented. The waveguides are fabricated by hot-embossing using a UV-cured epoxy resin stamper. The stamper is fabricated by replication of a rectangular groove mold that is made of silicone rubber replicated from a ridge original Si master that is fabricated by anisotropic etching of a (110) single-crystal Si. The optical waveguides with large core sizes from 100 μm to 500 μm are fabricated, and low propagation loss less than 0.2dB/cm at 650 nm is realized.
