Simultaneous detection of spin and orbital angular momentum of light through scattering from a single silver nanowire
Diptabrata Paul, Deepak K Sharma, G V Pavan Kumar
In recent times the spin angular momentum (SAM) and orbital angular momentum (OAM) of light have gained prominence because of their significance in optical communication systems, m…
Mirror-Coupled Microsphere can narrow the Angular distribution of Photoluminescence from WS2 Monolayers
Shailendra K. Chaubey, Sunny Tiwari, Gokul M. A. +3
Engineering optical emission from two dimensional, transition metal dichalcogenides (TMDs) materials such as Tungsten disulphide (WS2) has implications in creating and understandin…
Optothermal pulling, trapping, and assembly of colloids using nanowire plasmons
Vandana Sharma, Sunny Tiwari, Diptabrata Paul +3
Optical excitation of colloids can be harnessed to realize soft matter systems that are out of equilibrium. In this paper, we present our experimental studies on the dynamics of si…
Beaming Elastic and SERS Emission from Bent-Plasmonic Nanowire on a Mirror Cavity
Sunny Tiwari, Adarsh B. Vasista, Diptabrata Paul +2
We report on the experimental observation of beaming elastic and surface enhanced Raman scattering (SERS) emission from a bent-nanowire on a mirror (B-NWoM) cavity. The system was…
Mirror enhanced directional out-coupling of SERS by remote excitation of a nanowire-nanoparticle cavity
Sunny Tiwari, Adarsh B Vasista, Diptabrata Paul +1
We report on the experimental observation of mirror enhanced directional surface enhanced Raman scattering (SERS) from a self-assembled monolayer of molecules coupled to a nanowire…
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…
