Deterministic positioning of few aqueous colloidal quantum dots.

Emerging quantum technologies that critically require the integration of quantum emitters on photonic platforms are hindered by the control over their position, quantity, and scalability. Herein, we describe a facile strategy to deposit aqueous silica-coated quantum dots (QDs) in a template of polymethyl methacrylate (PMMA) nanoholes that leverages saturated ethanol vapor drop-casting and subsequent lift-off of the template. Ethanol vapor incorporation into water droplets during the drying process reduces the meniscus contact angle, which increases capillary forces and enhances particle confinement within the pinning contact region.

Surface plasmon hybridized dressed states.

Surface plasmon hybridization provides new perspectives for light manipulation at the nanoscale and related applications in nanophotonics. Multiple hybridization between metallic layers inside plasmonic nanocavities displays properties similar to atomic dressed states. In this Letter, we propose to numerically and analytically investigate the case of a multilayer structure composed of stacked metallic (M) and insulator (I) thin films.

Coupling a single dipole to a long-range surface plasmon device.

Embedding a thin layer of a noble metal between two symmetric media results in the hybridization of the surface plasmons, leading to the existence of a long-range surface plasmon (LRSP). In this Letter, we investigate numerically the coupling of a single dipole, as a probe, to this LRSP. Different de-excitation channels are available such as free space radiation and plasmonic modes in different proportions.
