ABSTRACT:
A plate plastics optical waveguide includes a core portion composed of a polymer containing a deuterium atom or a halogen atom, and a clad portion which surrounds the core portion and is composed of a polymer having a refractive index lower than that of the core portion. A plastics optical waveguide having a core portion comprising a deuterated or halogenated polyacrylate or polysiloxane shows an optical loss of 0.1 dB/cm or less for light having a wavelength of 1.3 .mu.m.
