Achieving tunable and coherent long-range interactions between cold atoms is an outstanding challenge. We propose a solution based on the powerful new platform of cold atoms trapped near nano-photonic systems. We show that atoms trapped near photonic crystals act as dielectric elements that seed localized cavity modes around the atomic position. This enables a dynamic form of “all-atomic” cavit...

Plasmonic structures open novel avenues in photodetector development. Optimized illumination configurations are reported to improve p-polarized light absorptance in superconducting-nanowire single-photon detectors (SNSPDs) comprising short- and long-periodic niobium-nitride (NbN) stripe-patterns. In OC-SNSPDs consisting of ~quarter-wavelength dielectric layer closed by a gold reflector the high...

Quantum dot/liquid crystal nano-composites are promising new materials for a variety of applications in energy harvesting, displays and photonics including the liquid crystal laser. To realize many applications, however, we need to control and stabilize nano-particle dispersion in different liquid crystal host phases and understand how the particles behave in an anisotropic fluid. An ideal syst...

We investigate the use of a metallic nano-cavity on dielectric waveguides for sensing applications. Nowadays the fabrication of metallic structures featured by challenging dimensions is feasible thanks to the most recent technologies such as EBeam Lithography (EBL) and lift-off [1]. We propose here to study the simulation, fabrication and characterization of such structures at the telecom wavel...

Host-guest interactions between cucurbit[7]uril (CB7) and a cardiotonic drug, milrinone, have been explored using steady state and pico-second time-resolved techniques. A novel fluorescence switch from ultraviolet (UV) to visible (cyan) is observed as a consequence of upward pKa shift of the drug inside the nano-cavity of cucurbit[7]uril.

The combination of trimesic acid and the tri-dentate linker 1,3,5-tri(4-pyridyl)-2,4,6-triazine leads to the assembly of a bilayer structure, which contains four pyrene molecules per cavity; adjacent tetrameric aggregates within the channels formed by the superimposed layers combine to yield pyrene nano-rods.

In this work, we performed an extensive theoretical and experimental study to unveil the underlying mechanisms related intensified transmittance in epsilon-near-zero (ENZ)-integrated plasmonic nano-apertures. The occurrence of phase singularities at incident side nano-apertures results reduction transmittance. We show that enhancement ENZ-integrated nano-slits is attributed annihilation by ENZ ...
