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…
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…
Directional emission from WS2 monolayer coupled to plasmonic Nanowire-on-Mirror Cavity
Shailendra K. Chaubey, Gokul M. A., Diptabrata Paul +3
Influencing spectral and directional features of exciton emission characteristics from 2D transition metal dichalcogenides by coupling it to plasmonic nano-cavities has emerged as…
Focused linearly-polarized light scattering from a silver nanowire: Experimental characterization of optical spin-Hall effect
Diptabrata Paul, Deepak K. Sharma, G. V. Pavan Kumar
Spin-orbit interactions (SOI) are a set of sub-wavelength optical phenomenon in which spin and spatial degrees of freedom of light are intrinsically coupled. One of the unique exam…
Large-scale optothermal assembly of colloids mediated by a gold microplate
Vandana Sharma, Diptabrata Paul, Shailendra K Chaubey +2
Light-activated colloidal assembly and swarming can act as model systems to explore non-equilibrium state of matter. In this context, creating new experimental platforms to facilit…
Dielectric microsphere coupled to a plasmonic nanowire: A self-assembled hybrid optical antenna
Sunny Tiwari, Chetna Taneja, Vandana Sharma +3
Hybrid mesoscale-structures that can combine dielectric optical resonances with plasmon-polaritons are of interest in chip-scale nano-optical communication and sensing. This experi…
