Second-harmonic generation for enhancing the performance of diffractive neural networks
Marie Braasch, Anna Kartashova, Elena Goi +3
Diffractive neural networks (DNNs) are an emerging approach for the realization of photonic artificial intelligence, especially due to their suitability for machine-vision applicat…
Enhanced photon-pair generation from a van der Waals metasurface
Tongmiao Fan, Yilin Tang, Shaun Lung +11
Quantum photon pairs play a pivotal role in many quantum applications. Metasurfaces, two-dimensional arrays of nanostructures, have been studied intensively to enhance and control…
Directionally Tunable Co- and Counter-Propagating Photon Pairs from a Nonlinear Metasurface
Maximilian A. Weissflog, Jinyong Ma, Jihua Zhang +6
Nonlinear metasurfaces have recently been established as a new platform for generating photon pairs via spontaneous parametric down-conversion. While for classical harmonic generat…
Nonlinear Nanoresonators for Bell State Generation
Maximilian A. Weissflog, Romain Dezert, Vincent Vinel +6
Entangled photon states are a fundamental resource for optical quantum technologies and investigating the fundamental predictions of quantum mechanics. Up to now such states are ma…
Nonlinear quantum spectroscopy with Parity-Time symmetric integrated circuits
