Characterizing crystalline defects in single Xe nanoparticles from angular correlations of single-shot diffracted X-rays

We performed a wide-angle X-ray scattering experiment of single Xe nanoparticles using an X-ray free electron laser. We developed a novel analysis method that focuses on the angular correlation between plural Bragg spots in single-shot diffraction patterns ...

Contactless optical trapping and manipulation of nanoparticles utilizing SIBA mechanism and EDL force

Mahdi Sahafi

On-chip optical tweezers based on evanescent fields overcome the diffraction limit of the free-space optical tweezers and can be a promising technique for developing lab-on-a-chip devices. While such trapping allows for low-cost and precise manipulation, i ...

Ultrafast generation and control of an electron vortex beam via chiral plasmonic near fields

Fabrizio Carbone, Giovanni Maria Vanacore, Ivan Madan, Enrico Pomarico, Gabriele Berruto, Ido Kaminer, Brett Eugene Barwick, Ebrahim Karimi

Vortex-carrying matter waves, such as chiral electron beams, are of significant interest in both applied and fundamental science. Continuous-wave electron vortex beams are commonly prepared via passive phase masks imprinting a transverse phase modulation o ...

Tilted-potential photonic crystal cavities for integrated quantum photonics

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Antoine Maxime Delgoffe, Alexey Lyasota, Bruno Marie Dominique Rigal, Alessio Massimiliano Davide Miranda

We propose and investigate a new type of photonic crystal (PhC) cavity for integrated quantum photonics, which provides tailored optical modes with both confined and extended spatial components. The structures consist of elongated PhC cavities in which the ...

Diffractive Optical Elements Investigation in the Phase Domain

Toralf Scharf, Myun Sik Kim, Dong Cheon Kim, Michail Symeonidis

In this work we demonstrate the advantages of investigating diffractive optical elements in the phase domain. In this regime we can detect features that are not restrained by the diffraction limit and relate them to the geometrical and optical properties o ...

Optical-stack optimization for improved SPAD photon detection efficiency

Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic, Ekin Kizilkan, Rolando Ferrini, Arin Can Ülkü, Scott Anthony Lindner, Marc Schnieper, Frédéric Zanella

Single-photon avalanche diodes (SPADs) are direct photon-to-digital detectors that enable scalable arrays with Poisson-limited signal-to-noise ratio and picosecond timing resolution. However, SPAD detectors require a guard-ring structure to prevent lateral ...

Patch Antenna System for CubeSats in L band

Anja Skrivervik, Miroslav Veljovic

An L-band patch-antenna system for CubeSat applications is presented in this paper. The high-permittivity dielectric loading reduces the size of individual antennas to make them suitable for a CubeSat platform. Two circularly polarized patch antennas were ...

Self-imaging of Azimuthal Intensity Petal Based on Orbital Angular Momentum Beams

Camille Sophie Brès, Jianqi Hu

We demonstrate for the first time azimuthal Talbot effect based on orbital angular momentum beams. The intensity petal is self-imaged in the azimuthal angle. We also draw the analogy between azimuthal and temporal Talbot effect. ...
