'Plasmonics' in free space: observation of giant wavevectors, vortices and energy backflow in superoscillatory optical fields
Guang Hui Yuan, Edward T. F. Rogers, Nikolay I. Zheludev
Evanescent light can be localized at the nanoscale by resonant absorption in a plasmonic nanoparticle or taper or by transmission through a nanohole. However, a conventional lens c…
Achromatic super-oscillatory lenses with sub-wavelength focusing
Guang Hui Yuan, Edward T. F. Rogers, Nikolay I. Zheludev
Lenses are crucial to light-enabled technologies. Conventional lenses have been perfected to achieve near-diffraction-limited resolution and minimal chromatic aberrations. However,…
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…
Quantum super-oscillation of a single photon
Guanghui Yuan, Stefano Vezzoli, Charles Altuzarra +4
Super-oscillation is a counter-intuitive phenomenon describing localized fast variations of functions and fields that happen at frequencies higher than the highest Fourier componen…
Optically Reconfigurable Photonic Devices
Qian Wang, Edward T. F. Rogers, Behrad Gholipour +4
Optoelectronic components with adjustable parameters, from variable-focal-length lenses to spectral filters that can change functionality upon stimulation, have enormous technologi…
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…
