Nonlinear Analog Processing with Anisotropic Nonlinear Films
Michele Cotrufo, Domenico de Ceglia, Hyunseung Jung +4
Digital signal processing is the cornerstone of several modern-day technologies, yet in multiple applications it faces critical bottlenecks related to memory and speed constraints.…
Skin effect in Non-Hermitian systems with spin
Wenna Zhang, Yutao Hu, Hongyi Zhang +6
The skin effect, where bulk modes collapse into boundary modes, is a key phenomenon in topological non-Hermitian systems, has been predominantly studied in spinless systems. Recent…
Intersubband polaritonic metasurfaces for high-contrast ultra-fast power limiting and optical switching
Michele Cotrufo, Jonas Krakofsky, Sander A. Mann +3
Nonlinear intersubband polaritonic metasurfaces support one of the strongest known ultrafast nonlinear responses in the mid-infrared frequency range across all condensed matter sys…
Temporal Signal Processing with Nonlocal Optical Metasurfaces
Michele Cotrufo, Sedigheh Esfahani, Dmitriy Korobkin +1
Nonlocal metasurfaces have recently enabled an ultra-compact, low-power and high-speed platform to perform analog image processing. While several computational tasks have been demo…
Space-Time Nonlocal Metasurfaces for Event-Based Image Processing
Sedigheh Esfahani, Michele Cotrufo, Andrea Alù
Analog computation with passive optical components can enhance processing speeds and reduce power consumption, recently attracting renewed interest thanks to the opportunities enab…
