Patent number: 10564091Abstract: An optical sensing device includes a substrate; a first dielectric layer extending thereon; a plurality of pairs of opposite antennas patterned on the first layer; and a second dielectric layer that covers all of the antennas. Opposite antennas are, in each of the pairs, separated by a gap g, which, on average, is between 1 nm and 50 nm, as measured in a direction x parallel to a main plane of the substrate. The pairs of antennas have different geometries. The second layer covers all the antennas and defines an electro-magnetic field enhancement volume between the opposite antennas of each of the pairs, thanks to the gap. Electro-magnetic radiation can be concentrated in each volume, making it possible to optically sense an analyte via opposite antennas of each of the pairs. Such a device allows analytes to be funneled and guided into the field-enhanced volumes for deterministic sensing.Type: GrantFiled: August 19, 2017Date of Patent: February 18, 2020Assignee: International Business Machines CorporationInventors: Cynthia Gruber, Lars Herrmann, Emanuel Marc Lörtscher, Bruno Michel, Lukas Novotny
