Optical forces in hybrid plasmonic waveguides.
We demonstrate that in a hybrid plasmonic system the optical force exerted on a dielectric waveguide by a metallic substrate is enhanced by more than 1 order of magnitude compared to the force between a photonic waveguide and a dielectric substrate. A nanoscale gap between the dielectric waveguide and the metallic substrate leads to deep subwavelength optical energy confinement with ultralow mo...
متن کاملPartial loss compensation in dielectric-loaded plasmonic waveguides at near infra-red wavelengths.
We report on the fabrication and characterization of straight dielectric-loaded surface plasmon polaritons waveguides doped with lead-sulfide quantum dots as a near infra-red gain medium. A loss compensation of ~33% (an optical gain of ~143 cm⁻¹) was observed in the guided mode. The mode propagation, coupling efficiency and stimulated emission were characterized using leakage radiation microsco...
متن کاملLoss compensation by spasers in plasmonic systems.
We show that in plasmonic systems, exact loss compensation can be achieved with the help of spasers pumped over a wide range of pumping values both below and above the spasing threshold. We demonstrate that the difference between spaser operation below and above the spasing threshold vanishes, when the spaser is synchronized by an external field. As the spasing threshold loses its significance,...
متن کاملSpaser, Plasmonic Amplification, and Loss Compensation
A review of quantum and gain nanoplasmonics is given. This includes spaser and plasmonic gain, amplification, and loss compensation. This Chapter reviews both fundamental theoretical ideas in quantum and gain nanoplasmonics and selected experimental developments. It is designed both for specialists in the field and general physics readership.
