Multipolar optical binding in focus
Ashutosh Shukla, Sneha Boby, G V Pavan Kumar
The optical binding of gold nanoparticles has conventionally been explored within the Rayleigh limit using dipole approximations. But the field is increasingly focusing on the Mie…
Evanescent Optothermoelectric Trapping: Deeper Potentials at a Largescale
Chaudhary Eksha Rani, Rahul Chand, Ashutosh Shukla +1
Surface plasmons (SP) and their mediated effects have been widely used to manipulate micro- and nanoscale objects of dielectric and metallic nature. In this work, we show how SP ex…
Opto-thermoelectric trapping of Fluorescent Nanodiamonds on Plasmonic Nanostructures
Ashutosh Shukla, Sunny Tiwari, Ayan Majumder +2
Deterministic optical manipulation of fluorescent nanodiamonds (FNDs) in fluids has emerged as an experimental challenge in multimodal biological imaging. Designing and developing…
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…
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…
Doughnut shaped emission from vertical organic nanowire coupled to thin plasmonic film
Adarsh B. Vasista, Ravi P. N. Tripathi, Shailendra K. Chaubey +2
Vertical nanowires facilitate an innovative mechanism to channel the optical field in the orthogonal direction and act as a nanoscale light source. Subwavelength, vertically orient…
