LUMPED PLASMONIC DIODE AND LUMPED PLASMONIC RECTIFIER FOR OPTICAL FIELD RECTIFICATION AND LUMPED OPTICAL SECOND HARMONIC GENERATION

摘要

A lumped nanocircuit element design at IR and optical frequencies is provided that can effectively act as a lumped "diode" and a lumped "rectifier" for rectifying optical field displacement currents or optical electric field. The lumped nanocircuit element design can also act as a lumped second harmonic generator. The element is formed by juxtaposing an epsilon-negative nanoparticle with a nonlinear optical nanostructure.
