Nonlinear Self-Action across Temporal Regimes in Resonant Dielectric Metasurfaces
Alfonso Nardi, Sonia Freddi, Michael Scalora +8
Quasi-bound states in the continuum (qBICs) enable exceptional field confinement, strongly reducing the pump intensity threshold for nonlinear light-matter interaction in dielectri…
Integrated electro-optic attention nonlinearities for transformers
Luis Mickeler, Kai Lion, Alfonso Nardi +5
Transformers have emerged as the dominant neural-network architecture, achieving state-of-the-art performance in language processing and computer vision. At the core of these model…
Efficient and tunable narrowband second-harmonic generation by a large-area etchless lithium niobate metasurface
Yaping Hou, Yigong Luan, Yu Fan +8
Optical resonances in nanostructures enable strong enhancement of nonlinear processes at the nanoscale, such as second-harmonic generation (SHG), with high- modes providing inte…
Mesoscopic light transport in nonlinear disordered media
Alfonso Nardi, Andrea Morandi, Romain Pierrat +4
Nonlinear disordered media uniquely combine multiple scattering and second-harmonic generation. Here, we investigate the statistical properties of the nonlinear light generated wit…
