Wavelength-selective nonlinear wavefront control in resonant thin-film lithium niobate metasurfaces
Madona Mekhael, Timo Stolt, Helena Weigand +4
Nonlinear metasurfaces offer compact control over frequency conversion and wavefront shaping. However, existing approaches, often based on geometric phase, lack wavelength selectiv…
Spatially-Controlled Planar Guided Crystallization of Low-Loss Phase Change Materials for Programmable Photonics
Fouad Bentata, Arnaud Taute, Capucine Laprais +14
Photonic integrated devices are progressively evolving beyond passive components into fully programmable systems, notably driven by the progress in chalcogenide phase-change materi…
Programmable metasurfaces for future photonic artificial intelligence
Loubnan Abou-Hamdan, Emil Marinov, Peter Wiecha +3
Photonic neural networks (PNNs), which share the inherent benefits of photonic systems, such as high parallelism and low power consumption, could challenge traditional digital neur…
Exploiting hidden singularity on the surface of the Poincaré sphere
Jinxing Li, Aloke Jana, Yueyi Yuan +3
The classical Pancharatnam-Berry phase, a variant of the geometric phase, arises purely from the modulation of the polarization state of a light beam. Due to its dependence on pola…
Observation of robust intrinsic C points generation with magneto-optical bound states in the continuum
Wenjing Lv, Haoye Qin, Zengping Su +6
C points, characterized by circular polarization in momentum space, play crucial roles in chiral wave manipulations. However, conventional approaches of achieving intrinsic C point…
