Abstract
An integrated plasmonic sensing device is described wherein the integrated device comprises: at least one optical source comprising a first conductive layer and a second conductive layer, and a optical active layer between at least part of said first and second conductive layers; at least one nanocavity extending through said first and second conductive layers and said optical active layer, wherein said optical source is configured to generate surface plasmon modes suitable for optically activating one or more resonances in said nanocavity; and, at least one optical detector comprising at least one detection region formed in said substrate in the vicinity of said nanocavity resonator, wherein said optical detector is configured to sense optically activated resonances in said nanocavity.
