Patent ID: 6867900

Claim:
A device for supporting chromophoric elements, comprising a substrate having an upper face on which said chromophoric elements are fixed and means for enhancing the quantity of light emitted by the chromophoric elements toward a collecting device, maid means being selected from a group consisting of: reflective means placed in the substrate at a distance from said upper face; microlenses each associated with a chromophoric clement and functioning in transmission or in reflection; diffraction means placed at a distance from the chromophoric elements and functioning in transmission or in reflection; first mirror means and second mirror means parallel to each other and placed on either side of the chromophoric elements to define an asymmetric resonant cavity; a planar wave guide formed in the substrate below the upper face carrying the chromophoric elements, to capture a portion of the light emitted by the chromophoric elements into the substrate and/or to supply excitation light; a configuration of the upper face of the substrate, formed as wells with a reflective bottom and filled with a material with a suitable index each receiving a chromophoric element; and planar resonators formed in the upper face of the substrate.
