Title (EN) COHERENT UPCONVERSION OF LIGHT
(FR) CONVERSION ASCENDANTE COHÉRENTE DE LUMIÈRE
Abstract:
(EN) Embodiments include an apparatus and method. An apparatus includes a metasurface that coherently upconverts light waves having a first frequency ƒ1. A substrate forms a first plasmonic surface. A plasmonic nanoparticle forms a second plasmonic surface. A layer of a second-order nonlinear dielectric material is disposed between the first plasmonic surface and the second plasmonic surface. The metasurface has at least three plasmonic resonant modes including a first plasmonic resonant mode having a first frequency ƒ1, a second plasmonic resonant mode having a second frequency ƒ2, and a third plasmonic resonant mode having a third frequency ƒ3 that is a sum of the first frequency ƒ1 and the second frequency ƒ2. The apparatus includes a second light propagation path from a source of pumped monochromatic coherent light waves having the second frequency ƒ2 to the metasurface. A digital image capture device captures the generated light waves having the frequency ƒ3.
(FR) Des modes de réalisation comprennent un appareil et un procédé. Un appareil comprend une métasurface qui convertit de manière cohérente des ondes lumineuses ayant une première fréquence ƒ1. Un substrat forme une première surface plasmonique. Une nanoparticule plasmonique forme une seconde surface plasmonique. Une couche d'un matériau diélectrique non linéaire de second ordre est disposée entre la première surface plasmonique et la seconde surface plasmonique. La métasurface comprend au moins trois modes résonants plasmoniques comprenant un premier mode résonant plasmonique ayant une première fréquence ƒ1, un second mode résonant plasmonique ayant une seconde fréquence ƒ2, et un troisième mode de résonance plasmonique ayant une troisième fréquence ƒ3 qui est une somme de la première fréquence ƒ1 et de la deuxième fréquence ƒ2. L'appareil comprend un second trajet de propagation de lumière à partir d'une source d'ondes de lumière cohérente monochromatique pompée ayant la seconde fréquence ƒ2 vers la métasurface. Un dispositif de capture d'image numérique capture les ondes lumineuses générées ayant la fréquence ƒ3.
