Claims37
A photodefinable composition comprising a silsesquioxane oligomer comprising as polymerized units a monomer of the formula (RSiO1.5) wherein R is selected from hydroxyphenyl or hydroxybenzyl;
- and a photoactive component, wherein the solubility of the silsesquioxane oligomer is altered upon exposure to actinic radiation.
A method of manufacturing an optical waveguide comprising the steps of:
- a) depositing on a substrate a layer of a photodefinable composition comprising a silsesquioxane oligomer comprising as polymerized units a monomer of the formula (RSiO1.5) wherein R is selected from hydroxyphenyl or hydroxyphenyl(C1-C5)alkyl;
- and a photoactive component;
- and b) exposing the composition to actinic radiation to form an optical waveguide.
An optical waveguide comprising a core and a cladding, wherein at least one of the core and cladding comprises a silsesquioxane polymer comprising as polymerized units a monomer of the formula (RSiO1.5) wherein R is selected from hydroxyphenyl or hydroxyphenyl(C1-C5)alkyl.
A photodefinable composition comprising a silsesquioxane oligomer comprising as polymerized units a monomer of the formula (RSiO1.5) wherein R is selected from hydroxyphenyl or hydroxybenzyl;
- one or more organic cross-linking agents;
- and a photoactive component, wherein the solubility of the silsesquioxane polymer is altered upon exposure to actinic radiation.
An optical waveguide comprising a core and a cladding, wherein at least one of the core and cladding comprises a silsesquioxane polymer comprising as polymerized units a monomer of the formula (RSiO1.5) wherein R is selected from hydroxyphenyl or hydroxybenzyl;
- and one or more organic cross-linking agents.
