Abstract:
1. A monomeric formulation for the fabrication of self-propagating polymer waveguides by photopolymerization, the monomeric formulation comprising: a first molecule comprising at least one C═C double bond or C≡C triple bond; a second molecule comprising two or more SH groups; a photoinitiator selected from the group consisting of 2,2-dimethoxy-2-phenylacetophenone; 2-hydroxy-2-methylpropiophenone; camphorquinone; benzophenone; and benzoyl peroxide, and combinations thereof; and a free radical inhibitor comprising a compound selected from the group consisting of methylhydroquinone, ethylhydroquinone, methoxyhydroquinone, ethoxyhydroquinone, monomethylether hydroquinone, propylhydroquinone, propoxyhydroquinone, tert-butylhydroquinone, n-butylhydroquinone, and combinations thereof, the free radical inhibitor being present at a positive amount between 0-3% by weight of the monomeric formulation, and the free radical inhibitor being present in an amount sufficient to reduce polymerization of the monomeric formulation outside the waveguides while propagating the polymer waveguides.
