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…
Generation of Diffraction-Free Optical Beams Using Wrinkled Membranes
Ran Li, Hui Yi, Xiao Hu +4
We report the first demonstration of wrinkled membranes as a kind of optical focusing devices, which are low cost, light weight and flexible. Our device consists of concentric wrin…
