Tunable emission from two-dimensional semiconductor with platelet optical antennas
… MoS 2 by coupling it with plasmonic platelet antennas, which can both convert freely propagating light into nanoscale and transmit radiation power into free space efficiently. The antennas used are single crystalline and the plasmonic modes are obtained both by near-field imaging and numerical …

Optical nano-antennas: Fabrication, characterization and applications
As optical counterpart of microwave antennas, optical nano-antennas are important devices for converting propagating radiation into confined/enhanced fields at nanoscale. The recent advances in resonant sub-wavelength optical antennas have now offered researchers a continuum of electromagnetic …

Optical Antenna Photovoltaics & Making Metallic Nano-rods
… that has not been widely explored is that of optical antennas. In 1972 Bailey et al.[1] explored scaling down of antenna technology to match the solar spectrum. A recent review was given by Lukas Novotny et al.[2], in which they outline the major hurdles as being the lack of reliable …

Towards quantum information processing with diamond color centers
… collection of the emitter's fluorescence. Optical antennas are appealing as they offer directional emission together with spontaneous emission rate enhancement across a broad emitter spectrum. We introduce and optimize metal-dielectric nano-antenna designs recessed into a diamond substrate …

Integrated optical phased arrays for lidar applications
It is no wonder that research in Si photonics (optical components embedded on a silicon platform) has bloomed so rapidly the last few years. Combining low loss, strong refractive index contrast (and, thus, light confinement), with electro-optical and thermo-optical effects, allows for the …
