Optical tweezers assisted coupling of nematic droplets to gold nanoparticle cluster: effect on whispering gallery modes
Sumant Pandey, G. V. Pavan Kumar
Dye doped liquid crystal (LC) microdroplets exhibit tunable optical resonances modulated by size, shape, temperature, and external perturbations. When a dye-doped nematic microdrop…
Brownian Colloids in Optothermal Field: An Experimental Perspective
G. V. Pavan Kumar
Colloidal matter undergoing Brownian motion serves as a model system to study various physical phenomena. Understanding the effect of external perturbation on the assembly and dyna…
Directing Monolayer Tungsten Disulfide Photoluminescence using a Bent Plasmonic Nanowire on a Mirror Cavity
Shailendra K. Chaubey, Sunny Tiwari, Ashutosh Shukla +3
Designing directional optical antennas without compromising the field enhancement requires specially designed optical cavities. Herein, we report on the experimental observations o…
Optoelectronic characterisation of twisted germanium sulfide nanowires with experimental observation of intrinsic ferroelectricity
Tamaghna Chowdhury, Aastha Vasdev, Goutam Sheet +1
We report the optoelectrical characterisation of Eshelby twisted Germanium sulfide (GeS) nanowires with first experimental observation of ferroelectric order at room temperature in…
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…
Wavevector analysis of plasmon-assisted distributed nonlinear photoluminescence along Au nanowire antennas
Deepak K. Sharma, Adrian Agreda, Julien Barthes +3
We report a quantitative analysis of the wavevector diagram emitted by nonlinear photoluminescence generated by a tightly focused pulsed laser beam and distributed along Au nanowir…
