Actively tunable bistable optical Yagi-Uda nanoantenna.
We propose and theoretically demonstrate a novel type of optical Yagi-Uda nanoantennas tunable via variation of the free-carrier density of a semiconductor disk placed in a gap of a metallic dipole feeding element. Unlike its narrowband all-metal counterparts, this nanoantenna exhibits a broadband unidirectional emission and demonstrates a bistable response in a preferential direction of the fa...
متن کاملShaping Light Beams in the Nanometer Scale: A Yagi-Uda Nanoantenna in the Optical Domain
A Yagi-Uda-like optical nanoantenna concept using resonant core-shell plasmonic particles as its “reflectors” and “directors” is studied numerically. Such particles when placed near an optical dipole source in a certain arrangement may exhibit large induced dipole moments, resulting in shaping the far-field radiation pattern, analogous to the far field of classical Yagi-Uda antennas in the micr...
متن کاملOptical spectrometer at the nanoscale using optical Yagi-Uda nanoantennas
Here we present and analyze an optical spectrum analyzer at the nanometer scale that is able to distribute different frequency contents of the radiation of an optical dipole source into different directions in the space. The spectrum analyzer is composed of arrays of optical Yagi-Uda nanoantennas, forming relatively narrow radiation patterns operating at different frequencies. The optical Yagi-...
متن کاملModified Two-element Yagi-uda Antenna with Tunable Beams
A modified two-element Yagi-Uda antenna with tunable beams in the H-plane (including four significant beams: forward, backward, omni-directional, and bi-directional beams) is presented. These tunable beams are achieved by simply adjusting the short-circuit position of the transmission line connected to the parasitic element. The principle of operation is investigated by examining the current re...
متن کاملAngular Radiation Patterns of Nanoantennas: an Optical Yagi-uda Antenna
We address experimentally the radiation patterns of quantum dots coupled to optical nanoantennas at specific positions. We show that the emission of the coupled system is determined by a variety of resonant and non-resonant antenna modes both in polarization and angular pattern. The first working optical Yagi-Uda antenna is presented and unidirectional emission is demonstrated for a limited spe...
