Title (EN) OPTICALLY TRANSMISSIVE DEVICES AND FABRICATION
(FR) DISPOSITIFS À TRANSMISSION OPTIQUE ET FABRICATION
Abstract:
(EN) An optical device as described herein includes a host substrate (115) fabricated from a dielectric material transparent in the Infrared range. Additionally, the optical device as discussed herein includes multiple elements (120) disposed on the host substrate. The multiple elements are spaced apart from each other on the host substrate in accordance with a desired pattern. Each of the multiple elements disposed in the host substrate is fabricated from a second material having a refractive index of greater than 4.5 such as PbTe. Such an optical device provides an improvement over conventional optical devices that operate in the Infrared range and forms a so called metasurface.
(FR) La présente invention concerne un dispositif optique qui comprend un substrat hôte (115) fabriqué à partir d’un matériau diélectrique transparent dans la plage infrarouge. En outre, le dispositif optique selon l’invention comprend de multiples éléments (120) disposés sur le substrat hôte. Les éléments multiples sont espacés les uns des autres sur le substrat hôte selon un motif souhaité. Chacun des éléments multiples disposés dans le substrat hôte est fabriqué à partir d’un deuxième matériau ayant un indice de réfraction supérieur à 4,5 tel que PbTe. Un tel dispositif optique permet une amélioration par rapport aux dispositifs optiques conventionnels qui fonctionnent dans la plage infrarouge et forme une "métasurface".
