Device for supporting chromophore elements
First Claim
1. A device for supporting chromophore elements suitable for emitting fluorescence in response to light excitation, the device comprising a substrate having a surface layer for carrying the chromophore elements and forming a planar waveguide, wherein the planar waveguide contains photoluminescent constituents suitable for emitting luminescence at the excitation wavelength(s) of the chromophore elements when said constituents are themselves excited by primary excitation light, the emitted luminescence being guided in the planar waveguide to excite the chromophore elements.

Abstract
A device for supporting chromophore elements suitable for emitting fluorescence in response to light excitation, the device comprising a substrate having a surface layer carrying the chromophore elements, forming a planar waveguide, and containing photoluminescent constituents which emit guided luminescence at the excitation wavelength(s) of the chromophore elements when they are excited by primary excitation light illuminating the surface layer. The invention is particularly applicable to biochip type devices.
