Reaching the optical propagation limit in temporal analog computing
Zeki Hayran
A central goal of optical computing is to perform calculations on the timescale of light propagation. Yet many analog photonic solvers require feedback, storage or field build-up b…

Pulse-driven photonic transitions and nonreciprocity in space-time modulated metasurfaces
Zeki Hayran, John B. Pendry, Prasad P. Iyer +1
Time-varying photonic systems open new possibilities for controlling light, enabling photonic time crystals, time reflection and refraction, frequency conversion, synthetic gauge f…
