Sub-Wavelength Plasmon Polaritons Channeling of Whispering Gallery Modes of Fluorescent Silica Microresonator
Sunny Tiwari, Chetna Taneja, G. V. Pavan Kumar
Herein, we report sub-wavelength propagation and directional out-coupling of whispering gallery modes (WGMs) of a fluorescent silica microsphere resonator mediated via plasmon pola…

Experimental observation of transverse spin of plasmon polaritons in a single-crystalline silver nanowire
Chetna Taneja, Diptabrata Paul, G V Pavan Kumar
We report the experimental observation of the transverse spin and associated spin-momentum locking of surface plasmon polaritons (SPPs) excited in a plasmonic single crystalline si…
