Quantum-Coherence-Enhanced Surface Plasmon Amplification by Stimulated Emission of Radiation
(American Physical Society, 2013)
We investigate surface plasmon amplification in a silver nanoparticle coupled to an externally driven three-level gain medium and show that quantum coherence significantly enhances the generation of surface plasmons. Surface ...
Near-Normal Incidence Dark-Field Microscopy: Applications to Nanoplasmonic Spectroscopy
(American Chemical Society, 2012)
The spectroscopic characterization of individual nanostructures is of fundamental importance to understanding a broad range of physical and chemical processes. One general and powerful technique that addresses this aim is ...
Metalenses at visible wavelengths: Diffraction-limited focusing and subwavelength resolution imaging
(American Association for the Advancement of Science, 2016)
Electrically pumped semiconductor laser with monolithic control of circular polarization
(National Academy of Sciences, 2014)
We demonstrate surface emission of terahertz (THz) frequency radiation from a monolithic quantum cascade laser with built-in control over the degree of circular polarization by " fishbone" gratings composed of orthogonally ...
Modeling nanoscale V-shaped antennas for the design of optical phased arrays
(American Physical Society, 2012)
We present a simplified numerical method to solve for the current distribution in a V-shaped antenna excited by an electric field with arbitrary polarization. The scattered far-field amplitude, phase, and polarization of ...
Thermal tuning of mid-infrared plasmonic antenna arrays using a phase change material
(Optical Society of America, 2013)
Spoof surface plasmon waveguide forces
(Optical Society of America, 2014)
Spoof surface plasmons (SP) are SP-like waves that propagate along metal surfaces with deeply sub-wavelength corrugations and whose dispersive properties are determined primarily by the corrugation dimensions. Two parallel ...
Broadband Multifunctional Efficient Meta-Gratings Based on Dielectric Waveguide Phase Shifters
(American Chemical Society, 2015)
Designed Quasi-1D Potential Structures Realized in Compositionally Graded InAs 1– x P x Nanowires
(American Chemical Society, 2016)
Vanadium Dioxide as a Natural Disordered Metamaterial: Perfect Thermal Emission and Large Broadband Negative Differential Thermal Emittance
(American Physical Society, 2013)
We experimentally demonstrate that a thin (approximately 150-nm) film of vanadium dioxide (VO2) deposited on sapphire has an anomalous thermal emittance profile when heated, which arises because of the optical interaction ...
