Hot carrier dynamics in a dispersionless plasmonic system
Banoj Kumar Nayak, S. S. Prabhu, Venu Gopal Achanta
Hot carrier dynamics in a dispersionless plasmonic structures over a broad wavelength are studied by pump-probe measurements with 45 fs time resolution. The role of direct excited…
Reflection confocal nanoscopy using a super-oscillatory lens
Arvind Nagarajan, L. Pjotr Stoevelaar, Fabrizio Silvestri +4
A Superoscillatory lens (SOL) is known to produce a sub-diffraction hotspot which is useful for high-resolution imaging. However, high-energy rings called sidelobes coexist with th…
Design, Fabrication and Characterization of nanoplasmonic lattice for trapping of ultracold atoms
Sunil Kumar, Manav Shah, Ajith P. Ravishankar +5
Ultracold atom-traps on a chip enhances the practical application of atom traps in quantum information processing, sensing, and metrology. Plasmon mediated near-field optical poten…
Microscopic Characterisation of Photo Detectors from CMS Hadron Calorimeter
R A Shukla, V G Achanta, P D Barbaro +6
The CMS hadron Calorimeter is made of alternating layers of scintillating tiles and metals, such as brass or iron. The original photo detectors were hybrid units with a single acce…
A Broadband Superabsorber at Optical Frequencies: Design and Demonstration
Arvind Nagarajan, Kumar Vivek, Manav Shah +2
Metasurface based super absorbers exhibit near unity absorbance. While the absorption peak can be tuned by the geometry/size of the sub-wavelength resonator, broadband absorption c…
Magnetoplasmonic Quasicrystals
Andrey N. Kalish, Roman S. Komarov, Mikhail A. Kozhaev +7
Nanostructured magneto-optical materials sustaining optical resonances open very efficient way for light control via magnetic field, which is of prime importance for telecommunicat…
