3D diffractive optics for linear interconnects and nonlinear processing
The optical domain presents potential avenues for enhancing both computing and communication due to its inherentproperties of bandwidth, parallelism, and energy efficiency. This research focuses on harnessing 3-Dimensional (3D)diffractive optics for novel ...
EPFL2024Ghost imaging using two SPAD array detectors: a parameter study towards the realization of a 3D quantum microscope
Edoardo Charbon, Claudio Bruschini, Paul Mos, Yang Lin
Quantum ghost imaging can be an important tool in making optical measurements. One of the most useful aspects of ghost imaging is the unique ability to correlate two sets of independently collected information. We aim to use the principles of ghost imaging ...
Spie-Int Soc Optical Engineering2024Fluorescence microscopy: A statistics-optics perspective
Fundamental properties of light unavoidably impose features on images collected using fluorescence microscopes. Accounting for these features is often critical in quantitatively interpreting microscopy images, especially those gathering information at scal ...
Amer Physical Soc2024Design Progress of Structural Components of the EU DEMO EC Equatorial Launcher
Jean-Philippe Hogge, René Chavan
The EU DEMO Tokamak is foreseen to be equipped with an electron cyclotron (EC) system for plasma heating, magnetohydrodynamic (MHD) control, and thermal instability suppression. Up to six launchers will be installed into equatorial ports with the aim to in ...
Piscataway2024Wave-momentum shaping for moving objects in heterogeneous and dynamic media
Romain Christophe Rémy Fleury, Matthieu Francis Malléjac, Bakhtiyar Orazbayev, Stefan Rotter
Light and sound waves can move objects through the transfer of linear or angular momentum, which has led to the development of optical and acoustic tweezers, with applications ranging from biomedical engineering to quantum optics. Although impressive manip ...
2024Strain engineering and strain measurement by spring tethers on suspended epitaxial GaN-on-Si photonic crystal devices
Suspended epitaxial gallium nitride (GaN) on silicon (Si) photonic crystal devices suffer from large residual tensile strain, especially for long waveguides, because fine structures tend to crack due to large stress. By introducing spring-like tethers, des ...
Bristol2024Direct Data-Driven Vibration Control for Adaptive Optics
Adaptive optics (AO) systems are used in ground- based telescopes to improve image resolutions, especially for long-exposure photography, by compensating for the effects of atmospheric turbulence and internal vibrations. Most current AO systems are based o ...
2023Microscopic origin of polarization-entangled Stokes-anti-Stokes photons in diamond
Christophe Marcel Georges Galland
Time-correlated Stokes-anti-Stokes (SaS) scattering has been studied in different transparent media, more frequently in diamond. While the nonclassical nature of the SaS scattered photons has been well established, the presence of entanglement in this spon ...
College Pk2023Symmetry and Rigidity for Boosting Erbium-Based Molecular Light-Upconversion in Solution
Jean-Claude Bünzli, Alexandre Fürstenberg
Previously limited to highly symmetrical homoleptic triple-helical complexes [Er(Lk)3]3+, where Lk are polyaromatic tridentate ligands, single-center molecular-based upconversion using linear optics and exploiting the excited-state absorption mechanism (ES ...
Weinheim2023Spun fibres: a quasi circularly birefringent medium
Luc Thévenaz, Ana Gabriela Correa Mena, Xu Cheng
A simplified model describing the polarisation characteristics of spun fibres is proposed, aiming at determining how close to a circularly birefringent medium such a fibre is. This is of crucial importance regarding the interest of such a medium for magnet ...
