Absorber of Topologically Structured Light
Luka Vignjevic, Eric Plum, Nikitas Papasimakis +1
Polarization- and wavelength-sensitive absorbers for homogeneous electromagnetic waves are crucial in photovoltaics, imaging and telecommunications. Here, we report on an absorber…
State Tomography of Toroidal Light Pulses
Luka Vignjevic, Yijie Shen, Nikitas Papasimakis +1
Toroidal pulses, also known as Focused or Flying Doughnuts (FDs), are few-cycle pulses of doughnut-like topology. Originally proposed by Hellwarth and Nouchi in 1996, they have rec…
Infrared dielectric metamaterials from high refractive index chalcogenides
H. N. S. Krishnamoorthy, G. Adamo, J. Yin +3
High-index dielectric materials are in great demand for nanophotonic devices and applications, from ultrathin optical elements to metal-free sub-diffraction light confinement and w…
Unlabelled Far-field Deeply Subwavelength Superoscillatory Imaging (DSSI)
T. Pu, V. Savinov, G. Yuan +2
Recently it was reported that deeply subwavelength features of free space superoscillatory electromagnetic fields can be observed experimentally and used in optical metrology with…
Spontaneous natural optical activity in disordered media
F. A. Pinheiro, V. A. Fedotov, N. Papasimakis +1
We demonstrate natural optical activity in disordered ensembles of non-chiral plasmonic resonators. We show that the statistical distributions of rotatory power and spatial dichroi…
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…
