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…
Quantum logical controlled-NOT gate in a lithium niobate-on-insulator photonic quantum walk
Robert J. Chapman, Samuel Häusler, Giovanni Finco +2
Quantum computers comprise elementary logic gates that initialize, control and measure delicate quantum states. One of the most important gates is the controlled-NOT, which is wide…
Polarization dynamics of solid-state quantum emitters
Anand Kumar, Çağlar Samaner, Chanaprom Cholsuk +10
Quantum emitters in solid-state crystals have recently attracted a lot of attention due to their simple applicability in optical quantum technologies. The polarization of single ph…
Nonlinear Optical Data Transformer for Machine Learning
Mustafa Yildirim, Ilker Oguz, Fabian Kaufmann +4
Modern machine learning models use an ever-increasing number of parameters to train (175 billion parameters for GPT-3) with large datasets to obtain better performance. Bigger is b…
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…
Broadband photon pair generation from a single lithium niobate microcube
Ngoc My Hanh Duong, Gregoire Saerens, Flavia Timpu +8
Nonclassical light sources are highly sought after as they are an integral part of quantum communication and quantum computation devices. Typical sources rely on bulk crystals that…
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…
How to organize an online conference
Orad Reshef, Igor Aharonovich, Andrea Armani +4
On January 13th 2020, the inaugural Photonics Online Meetup (POM) brought together more than 1100 researchers to discuss the latest advances in photonics. Or rather, it didn't, bec…
Anapoles in Free-Standing III-V Nanodisks Enhancing Second-Harmonic Generation
Maria Timofeeva, Lukas Lang, Flavia Timpu +5
Nonradiating electromagnetic configurations in nanostructures open new horizons for applications due to two essential features: lack of energy losses and invisibility to the propag…
