Quantum-Coherence-Enhanced Surface Plasmon Amplification by Stimulated Emission of Radiation
Konstantin E. Dorfman, Pankaj K. Jha, Dmitri V. Voronine +3
We investigate surface plasmon amplification in a silver nanoparticle coupled to an externally driven three-level gain medium, and show that quantum coherence significantly enhance…
Aberration-free ultra-thin flat lenses and axicons at telecom wavelengths based on plasmonic metasurfaces
Francesco Aieta, Patrice Genevet, Mikhail A. Kats +4
The concept of optical phase discontinuities is applied to the design and demonstration of aberration-free planar lenses and axicons, comprising a phased array of ultrathin subwave…
Giant birefringence in optical antenna arrays with widely tailorable optical anisotropy
Mikhail A. Kats, Patrice Genevet, Guillaume Aoust +5
The manipulation of light by conventional optical components such as a lenses, prisms and wave plates involves engineering of the wavefront as it propagates through an optically-th…
