Tunable polarization-entangled near-infrared photons from orthogonal GaAs nanowires
Elise Bailly-Rioufreyt, Zoya Polshchykova, Grégoire Saerens +10
Quantum entanglement is a fundamental resource for emerging quantum technologies, enabling secure communication and enhanced sensing. For decades, generating polarization entangled…
Polarization-entangled photon pair generation from an epsilon-near-zero metasurface
Wenhe Jia, Grégoire Saerens, Ülle-Linda Talts +5
Polarization-entangled photon pair sources are essential for diverse quantum technologies, such as quantum communication, computation, and imaging. However, the generation of compl…
Second-Order Nonlinear Circular Dichroism in Square Lattice Array of Germanium Nanohelices
Grégoire Saerens, Günter Ellrott, Olesia Pashina +5
Second harmonic generation (SHG) is prohibited in centrosymmetric crystals such as silicon or germanium due to the presence of inversion symmetry. However, the structuring of such…
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…
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…
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…
