Plate plastics optical waveguide.

摘要

A plate plastics optical waveguide comprises a core portion (3) composed of a polymer containing a deuteriumation or a halogen atom, and a clad portion (2,7) which surrounds the core portion and composed of a polymer having a refractive index lower than that of the core portion. The plastics optical waveguide which has a core portion comprising a deuterated or halogenated polyacrylate or polysiloxane shows an optical loss of 0.1 dB/cm or less for a light at a wavelength of 1.3 mu m.
