All-optical free-space routing of upconverted light by metasurfaces via nonlinear interferometry
Agostino Di Francescantonio, Attilio Zilli, Davide Rocco +9
All-optical modulation yields the promise of high-speed information processing. In this frame, metasurfaces are rapidly gaining traction as ultrathin multifunctional platforms for…
Effective bath model for arrays of coupled non-Hermitian nanoresonators
Vincent Vinel, Zejian Li, Adrien Borne +4
Nanophotonics systems have recently been studied under the perspective of non-Hermitian physics. Given their potential for wavefront control, nonlinear optics and quantum optics, i…
Infrared up-conversion imaging in nonlinear metasurfaces
Rocio Camacho-Morales, Davide Rocco, Lei Xu +15
Infrared imaging is a crucial technique in a multitude of applications, including night vision, autonomous vehicles navigation, optical tomography, and food quality control. Conven…
Fundamental limitations of Huygens metasurfaces for optical beam shaping
Carlo Gigli, Qitong Li, Pierre Chavel +3
Optical dielectric metasurfaces composed of arrayed nanostructures are expected to enable arbitrary spatial control of incident wavefronts with subwavelength spatial resolution. Fo…
Quasinormal-mode modeling and design in nonlinear nano-optics
Carlo Gigli, Tong Wu, Giuseppe Marino +3
Based on quasinormal-mode theory, we propose a novel approach enabling a deep analytical insight into the multi-parameter design and optimization of nonlinear photonic structures a…
Spontaneous photon-pair generation at the nanoscale
Giuseppe Marino, Alexander S. Solntsev, Lei Xu +13
Optical nanoantennas have shown a great capacity for efficient extraction of photons from the near to the far-field, enabling directional emission from nanoscale single-photon sour…
