Abstract
Light detectors that combine field emission with light focusing by surface plasmon polaritons. Methods and devices that allow detection and measurement of light at high frequencies in the THz range are described. The disclosed devices include plasmonic metal contacts with a narrow nanometer-sized gap to couple an optical waveguide mode into a plasmonic mode thereby generating filed emission currents by biasing the contacts.
