Synthesis and Characterization of Methyl Methacrylates-Based Copolymers Containing Crosslinkable Pendant Groups for Optical Waveguides

摘要

Recently, polymeric optical waveguides have been widely utilized in the optical industry for various optical interconnects, optical communication components and intergrated optics. In comparison with inorganic materials such as lithium niobate and silica, polymeric materials have many advantages as an optical waveguide: flexibility, easy control of refractive index, and simple and low-cost fabrication process, to name only a few. However, most polymers consisted of hydrocarbons show a large transmission loss in near-IR region due to the vibrational overtone absorption of C-H bonds. Therefore, deuterated or fluorinated polymers have been investigated as materials for low optical loss. Deuterated or halogenated poly(methyl methacylate), fluorinated polyimides, fluorinated poly(aryl ether)s, perfluorocyclobutane (PFCB) aryl ether polymers, and highly fluorinated acrylates have been studied for use of as waveguides.
