Crosslinkable material containing a chromophore, crosslinked material, optical integrated circuit comprising said material and method for preparing same

摘要

The invention concerns a material capable of being light-cured and micro-structured entirely or partly by visible light essentially comprising a monomer matrix having at least three crosslinkable functions, said matrix containing a chromophore and a photosensitizer exhibiting an absorption peak in the distinct visible domain, separate from that of the chromophore, said material being capable, when crosslinked, of exhibiting, in the crosslinked part, a local increase of viscosity and of refractive index. The invention also concerns a crosslinked material entirely or partly micro-structured by visible light of the crosslinkable material, said material exhibiting in the crosslinked part a local increase of viscosity and of refractive index. The invention further concerns an optical integrated circuit comprising said crosslinked material and a method for preparing said circuit.
