Abstract:
1. A planar optical structure having an evanescent-field measuring platform, wherein said evanescent-field measuring platform comprises a multilayer system that has: at least one of a metal layer and an essentially optically transparent wave guiding layer, said at least one of a metal layer and an essentially optically transparent wave guiding layer having a refractive index n at least an essentially optically transparent second layer with a refractive index n at least one optical coupling grating for in-coupling of excitation light, wherein said essentially optically transparent second layer comprises a thermoplastic plastic selected from the group consisting of cyclo-olefin polymers and cyclo-olefin copolymers, wherein said optical coupling grating is formed by the process of molding said optical coupling grating into said essentially optically transparent second layer from a master.
