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…
Simultaneous Superoscillations in Space and Time in Nonseparable Light Pulses
Yijie Shen, Nikitas Papasimakis, Nikolay I. Zheludev
A remarkable phenomenon of superoscillations implies that electromagnetic waves can locally oscillate in space or time faster than the fastest spatial and temporal Fourier componen…
