The present invention provides a method for forming an optical coupling device
on a substrate by disposing a material onto the substrate that is polymerizable
in response to actinic radiation. A stack of the material is formed by contacting
the material with a template having a stepped-recess formed therein. The material
is then solidified into an optically transparent body with a surface having a plurality
of steps by subjecting the stack to actinic radiation. To that end, the material
may comprise an acrylate component selected from a set of acrylates consisting
essentially of ethylene dio diacrylate, t-butyl acrylate, bisphenol A diacrylate,
acrylate terminated polysiloxane, polydifluoromethylene diacrylate, perfluoropolyether
diacrylates and chlorofluorodiacrylates. Alternatively, the material may include
a silylated component selected from a group consisting essentially of (3-acryloxypropyltristrimethylsiloxy) silane.
