碩士 === 國立交通大學 === 光電工程系所 === 92 === Polymer with low propagation loss, high glass transition temperature (Tg), and high thermo-optic coefficient ( ) have been used worldwide for photonic components. In this paper, a polymer waveguide type variable optical attenuator fabricated by molding glass technology is proposed. The S-shape buried waveguide structure with polymer core and silica cladding that attenuates light with satisfactory optical attenuation through the spectrum from 1.52�慆 to 1.57�慆 is presented. The waveguide bend design is fabricated by photolithography、electroforming and molding glass technologies and operates by controlling waveguide bend radiation loss. This device has 30db attenuation（-1dB/℃）after we carry out that device. In addition, this design is suitable to integrate with planar light-wave circuits（PLC）to fabricate the monolithic optical modules in application of optical communication
