Abstract

Optical nano-antennas have become a hot topic in photonics research recently due to their ability to manipulate electromagnetic radiation on the subwavelength scale. Of particular interest is the application of optical nano-antennas to enhancement of quantum sources such as semiconductor Quantum Dots (QD) and Nitrogen Vacancy (NV) centers in nano-diamond. Much like their Radio Frequency (RF) cousins, optical nano-antennas are able to enhance and direct radiation from a localized source in the near-field of the antenna to the far-field. The work reported here exploits RF antenna designs by applying them to the development of optical nano-antennas for enhancement of multiple semiconductor QDs...
