Abstract: A curable composition and a process for using the curable composition within a grating-coupled waveguide (GCW) sensor are disclosed. The composition can be used for facile replication of optical components, specifically those used in a label-independent detection system where operation of the waveguide is dependent on the detailed formation of micro and nano size patterns. The photo or electron beam curable composition has low viscosity (?500 cPs) and cures to an optically clear material with high glass transition temperature (?70° C.), low shrinkage on cure, low outgassing, and low extractables.
