    摘要: A polymeric optical material which is a mixture of a polysiloxane and at least one compound selected from the group consisting of polyisocyanate, silane, alkoxide and chelate, and an optical waveguide fabricated from the polymeric optical material having high thermal stability and low propagation loss over wide range. The polysiloxane may have, for example, a repeating unit of following formula (I): ##STR1## wherein each of R.sub.1 and R.sub.2 is independently an alkyl, deuterated alkyl or halogenated alkyl group, or a phenyl, deuterated phenyl or halogenated phenyl group. The optical waveguide includes a substrate, a clad layer provided on the substrate and a core layer surrounded by the clad layer. The clad layer is composed of a lower clad layer which is overlaid onto the substrate and an upper clad layer which surrounds the core layer.
