Claim Text:
1. An image sensor comprising a plurality of sensor elements, at least one sensor element in the plurality of sensor elements comprising: a substrate comprising a depletion region; and at least one detector element disposed on the substrate, the at least one detector element comprising at least one resonator structure, the at least one resonator structure comprising at least two conductive structures separated by a spacing, wherein the at least one sensor element is configured such that charge carriers are generated in a region of the substrate near the spacing based on an enhanced electric field induced in the spacing by a resonant response of the at least one resonator structure to a presence of target electromagnetic radiation; wherein a thickness of the substrate is configured such that the charge carriers are generated in the depletion region when the image sensor is illuminated by the target electromagnetic radiation; and wherein the image sensor is configured to measure a conductivity based on the generated charge carriers as an indication of the presence of the target electromagnetic radiation.
