Abstract:
1. A method of producing a planar multimode optical waveguide by direct photo-patterning, comprising: applying a photosensitive organic-inorganic hybrid material layer for the multimode optical waveguide onto a substrate in a thickness of 10 microns or more, the organic-inorganic hybrid material comprising oligosiloxane having one or more organic functional groups capable of being polymerized selected from the group consisting of an acryl functional group, a methacryl functional group, an allyl functional group, a vinyl functional group, and an epoxy functional group, and at least one of an organic monomer which is capable of forming a polymer and a photoinitiator which forms dimmers upon light radiation to initiate polymerization; patterning the applied photosensitive organic-inorganic hybrid material; and radiating light having a predetermined wavelength range onto the patterned photosensitive organic-inorganic hybrid material layer to form the multimode optical waveguide having a structure that is 10 microns or more long and 10 microns or more wide by refractive index modulation between regions onto which light is and is not radiated.
