| Zusammenfassung: | A guided mode resonance device, comprising-a substrate,-a waveguide,-a grating structure associated with said waveguide, said grating structure being arranged to an incident surface of said substrate, said incident surface being intended to receive an incident light beam provided by at least one light source, said incident light beam having an incident angle, defined relative to the normal of said waveguide, said grating structure comprising at least one elementary structure comprising at least a first-type grating structure and at least a second-type grating structure,-wherein:-said waveguide is arranged to transfer light from the first-type grating structures to the second-type grating structure and also to transfer light from the second-type grating structures to the first-type grating structure,-said first-type grating structure is arranged to couple out a first light beam,-said second-type grating structure is arranged to couple out a second light beam,-said first light beam having a different spectral distribution than said second light beam. |
