2D-Material-Assisted Bistable Switching of Gap Plasmons Disclosed By Femtosecond Pulse Scattering Spectra
Tian Yang, Hui Yi, Xiaodan Wang +5
Nanosphere-on-mirror plasmonic antennas, each having a monolayer graphene or MoS2 sheet in the gap, were pumped with a femtosecond laser. Abrupt turnings in the scattering linewidt…
Quadruple-enhanced four-wave mixing in nanometer plasmonic hotspots: classical theory and experiments
Hui Yi, Xiaodan Wang, Tian Yang
Efficiency is a critical factor limiting the applications of nonlinear plasmonic devices. We show by theory and experiments that high efficiency four-wave mixing (FWM) is achieved…
Reproducible Ultrahigh Electromagnetic SERS Enhancement in Nanosphere-Plane Junctions
Jing Long, Hui Yi, Hongquan Li +1
Surface enhanced Raman scattering (SERS) in nanoscale hotspots has been placed great hopes upon for identification of minimum chemical traces and in-situ investigation of single mo…
Plasmonic Crystal Cavity on Single-Mode Optical Fiber End Facet for Label-Free Biosensing
Xiaolong He, Hui Yi, Jing Long +3
All surface plasmon resonance (SPR) devices on single-mode optical fibers' (SMF) end facets, as reported up to date, are limited by severely broad and shallow resonance spectra. Th…
Gap plasmon resonator arrays for unidirectional launching and shaping of surface plasmon polaritons
Zeyu Lei, Tian Yang
We report the design and experimental realization of a kind of miniaturized devices for efficient unidirectional launching and shaping of surface plasmon polaritons (SPPs). Each de…
