Abstract
An implantable optical sensor comprises a photonic integrated circuit comprising a substrateand an optical microstructureintegrated with the substrate. The optical microstructure is positioned to form an exposed optical interaction areaon a part of a surfaceof the substrate. A cover capis sealed onto a part of the substrateadjacent to the optical interaction areaand by wafer-to-wafer bonding technology or another wafer-level hermetic packaging technique. At least one active componentis positioned in a sealed cavitywhich is formed between the surfaceand the cover cap. The substratecomprises at least one optical feedthrough, which is an embedded waveguide extending from the sealed cavityto the optical interaction area
