Pulley-type metallic microring surface plasmon polariton sensor based on Otto-configuration
Results in Physics, 2019 In this study, we design a compact sensor with high sensitivity for refractive index change. A pulley-type metallic microring to produce surface plasmon polariton is proposed. The light is coupled onto the metallic microring using a dielectric waveguide.

Plasmons polaritons de surface
Photoniques, 2022 La plasmonique est l’étude de l’interaction entre les électrons libres d’un métal et la lumière. Les plasmons polaritons de surface sont des modes plasmoniques localisés au niveau d’une interface entre un métal et un diélectrique. Ces ondes évanescentes, qui peuvent être obtenues expérimentalement par différentes approches, ont des propriétés de ...

Low-loss Airy surface plasmon polaritons [PDF]
Chinese Optics Letters, 2015 We propose a scheme to obtain a low-loss propagation of Airy surface plasmon polaritons (SPPs) along the interface between a dielectric and a negative-index metamaterial (NIMM). We show that, by using the transverse-magnetic mode and the related destructive interference effect between electric and magnetic absorption responses, the propagation loss of ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics
Advanced Materials, EarlyView.The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and
