Abstract

The extremely small size of plasmonic antennas has made it difficult to integrate them with nanoscale detectors that require electrical leads, as the leads tend to degrade the resonant properties of the antenna. We present a design for integrating a plasmonic antenna with a nanoscale superconducting transition-edge sensor (TES) with electrical leads. Numerical simulations demonstrate high-efficiency coupling of 1550 nm incident photons into the sub-wavelength TES. Although we have chosen to design around a TES, this approach is broadly applicable to any dissipative nanoscale device that requires an electrical connection.
