Abstract :
An optical antenna, e.g., a metal structure of nanometer size enhances the effective scattering cross-section of molecule for single photon. We theoretically analyzed two-photon up-conversion process on four-level diamond-shaped systems coupled with an optical antenna, and found significant enhancement of the up-conversion.
