Abstract
Conference Title: 2015 Conference on Lasers and Electro-Optics (CLEO) Conference Start Date: 2015, May 10 Conference End Date: 2015, May 15 Conference Location: San Jose, CA, USA We investigate the plasmonic nanodipole antenna with sub-microscopic nanogap. Relevant quantum conductivities, including both linear and nonlinear components, are observed due to the photon-assisted quantum tunneling, realizing optical nano-radiators with enhanced amplitude and frequency modulations.
