By utilizing an analytical effective medium and an exact numerical approaches we design a magnetoplasmonic hyperbolic metamaterial with broadband nonreciprocal response. It is shown that such metamaterial, with reduced spatial symmetry and the time-reversal symmetry broken by magnetization, exhibits multiple nonreciprocal hyperbolic regimes. Magnetization induced one-way topological phase transitions...
We demonstrate simultaneous enhancement in spontaneous emission rate and light extraction from hyperbolic metamaterials embedded with quantum dots using a high contrast grating. Enhancements of twenty-fold in extraction and thirteen-fold in emission rate are observed.
We report preferential emission from ZnO nanoparticles into an epsilon near zero metamaterial. The structure is designed to have the parallel component of its dielectric constant approach zero at the maximum emission wavelength of ZnO.
We demonstrate one-dimensional dielectric micro cavity embedded with a monolayer of molybdenum disulfide. Enhanced directionality in light emission due to the interaction of micro cavity photons with the two-dimensional excitons is observed.
Directional light extraction from high-k modes in a hyperbolic metamaterial (HMM) is demonstrated by direct coupling of resonance cones from quantum dots (QDs) underneath a metal-dielectric composite to a high index bulls-eye grating structure.
We demonstrate strong light-matter coupling in a monolayer molybdenum disulfide (MoS2) based microcavity at room temperature. A Rabi splitting of 46 meV and highly directional emission is observed from the MoS2 microcavity.
We report on the experimental observation of dynamical collapses which address selectively the TM-mode of a laser subject to optical feedback with variably rotated polarization. Simultaneously, the TE-mode which remains the dominant lasing mode exhibits power bursts. We analyze the relative phase shift between the feedback fields into the TE- and TM-mode and find that the dynamical collapses, observed...
