Dynamic metasurface lens based on MEMS Technology
Tapashree Roy, Shuyan Zhang, Il Woong Jung +3
In the recent years, metasurfaces, being flat and lightweight, have been designed to replace bulky optical components with various functions. We demonstrate a monolithic Micro-Elec…
Luminescence engineering in plasmonic meta-surfaces
Tapashree Roy, Edward T. F. Rogers, Nikolay I. Zheludev
Photoluminescence is a phenomenon of significant interest due to its wide range of technological applications in plasmonics, nanolasers, spasers, lasing spasers, loss compensation…
Sub-wavelength focusing meta-lens
Tapashree Roy, Edward T. F. Rogers, Nikolay I. Zheludev
We show that planar a plasmonic metamaterial with spatially variable meta-atom parameters can focus transmitted light into sub-wavelength hot-spots located beyond the near-field of…
