Nearly perfect 90-degree bends and T-splitters are demonstrated in plasmonic nano-coaxial waveguides at the telecommunication wavelength, with bending and splitting efficiencies greater than 97% and 99%, respectively.
We show that the thermal emission of a finite-size blackbody emitter can be enhanced. We experimentally observe a four-fold enhancement of the far-field thermal emission of a carbonblack emitter having an emissivity of 0.85.
We propose a temporal coupled mode theory for thermal emission from a single emitter. We validate the coupled mode theory formalism by a direct numerical simulation of the emission properties of single emitters.
We extend the quantum input-output formalism for a qubit embedded in a waveguide to derive analytical formulas for the first- and second-order statistics of the scattered fields for an arbitrary intensity coherent state input.
We demonstrate numerically the ability to design a phase front using an array of metallic pillars. We show that in such structures, the local phase delay upon transmission can be tuned by local geometry.
The optical properties of nanoscale apertures in optically thick metallic films have been intensely researched in the past years due to their fundamental importance in near-field optics. Here, we show that the entire dispersion behavior of a plasmonic structure with coaxial cross-section i.e., formed by a dielectric ring between a metallic core and a metallic cladding, is well-approximated by a simple...
