Sol-gel Barium Titanate Nanohole Array as a Nonlinear Metasurface and a Photonic Crystal

Ülle-Linda Talts, Helena C. Weigand, Grégoire Saerens +6

The quest of a nonlinear optical material that can be easily nanostructured over a large surface area is still ongoing. Here, we demonstrate a nanoimprinted nonlinear barium titana…

Graph model for multiple scattering in lithium niobate on insulator integrated photonic networks

Xiyue Sissi Wang, Romolo Savo, Andreas Maeder +6

We present a graph-based model for multiple scattering of light in integrated lithium niobate on insulator (LNOI) networks, which describes an open network of single-mode integrate…

Second-harmonic generation tuning by stretching arrays of GaAs nanowires

Grégoire Saerens, Esther Bloch, Kristina Frizyuk +7

We present a wearable device with III-V nanowires in a flexible polymer, which is used for active mechanical tuning of the second-harmonic generation intensity. An array of vertica…

Enhanced electro-optic modulation in resonant metasurfaces of lithium niobate

Helena Weigand, Viola V. Vogler-Neuling, Marc Reig Escalé +5

In display technologies or data processing, planar and subwavelength free-space components suited for flat photonic devices are needed. Metasurfaces, which shape the optical wavefr…

Modeling of Random Quasi-Phase-Matching in Birefringent Disordered Media

Jolanda S. Müller, Andrea Morandi, Rachel Grange +1

We provide a vectorial model to simulate second-harmonic generation (SHG) in birefringent, transparent media with an arbitrary configuration of non-linear () crystalline g…

Broadband Mie-driven random quasi-phase-matching

Romolo Savo, Andrea Morandi, Jolanda S. Müller +6

High-quality crystals without inversion symmetry are the conventional platform to achieve optical frequency conversion via three wave-mixing. In bulk crystals, efficient wave-mixin…
