The performance requirements of polymer waveguides used in optical telecommunication and their future opportunities are discussed. Me polymer waveguide is suited for mass production and has an excellent cost performance ratio,therefore, it is to be utilized in the home terminals of FTTH. Fluorinated polyimides will be used for these terminals because they have good optical properties, high heat resistance, and long-term reliability. We have fabricated the fluorinated polyimide planar lightwave circuit integrated with V-groove contributing to high throughput assembly and automated manufacturing of high performance transceiver modules, and confirmed it accurate enough for optical network units.
