Single-shot Kramers-Kronig complex orbital angular momentum spectrum retrieval
Camille Sophie Brès, Jianqi Hu, Yujie Chen
Orbital angular momentum (OAM) spectrum diagnosis is a fundamental building block for diverse OAM-based systems. Among others, the simple on-axis interferometric measurement can retrieve the amplitude and phase information of complex OAM spectra in a few s ...
SPIE-SOC PHOTO-OPTICAL INSTRUMENTATION ENGINEERS2023Topological MIMO Optical Signal Processing
Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad
An important advantage of optical signal processing is the possibility of performing various operations in parallel. Among the techniques proposed for parallel optical signal processing, frequency division multiplexing (FDM) is a well-known approach, in wh ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Improved calorimetric particle identification in NA62 using machine learning techniques
Alessandro Mapelli, Radoslav Marchevski, Alina Kleimenova
Measurement of the ultra-rare K+ -> pi(+)nu(nu) over bar over bar decay at the NA62 experiment at CERN requires high-performance particle identification to distinguish muons from pions. Calorimetric identification currently in use, based on a boosted decis ...
New York2023Generation of OAM-carrying space-time wave packets with time-dependent beam radii using a coherent combination of multiple LG modes on multiple frequencies
Tobias Kippenberg, Maxim Karpov, Zhe Zhao, Hao Song, Xinzhou Su
Space-time (ST) wave packets, in which spatial and temporal characteristics are coupled, have gained attention due to their unique propagation characteristics, such as propagation invariance and tunable group velocity in addition to their potential ability ...
Optica Publishing Group2022Active Ferromagnetic Metasurface with Topologically Protected Spin Texture for Spectral Filters
Dirk Grundler, Haiming Yu, Jilei Chen
Electromagnetic metasurfaces modulate a material's response to electromagnetic waves by specifically arranged elements with dimensions below the wavelength. They have opened new fields of research, including flat optics and nanophotonics on a chip. Ferroma ...
