Strong optical coupling in metallo-dielectric hybrid metasurfaces
Ajith P Ravishankar, Felix Vennberg, Anand Srinivasan
Metasurfaces consisting of hybrid metal/dielectric nanostructures carry advantages of both material platforms. The hybrid structures can not only tightly confine subwavelength elec…
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…
Metasurfaces for suppressing reflection over broadband
Anuradha Patra, Ajith P. Ravishankar, Arvind Nagarajan +1
Surfaces patterned with arrays of quasi-periodic air holes having conical depth profile have been studied for their effectiveness in suppressing air-substrate reflection in the wav…
