Dual-Output Mode Analysis of Multimode Laguerre-Gaussian Beams via Deep Learning

Optics, 2021
The Laguerre-Gaussian (LG) beam demonstrates great potential for optical communication due to its orthogonality between different eigenstates, and has gained increased research interest in recent years. Here, we propose a dual-output mode analysis method

Role of surface microgeometries on electron escape probability and secondary electron yield of metal surfaces [PDF]

, 2020
The influence of microgeometries on the Secondary Electron Yield (SEY) of surfaces is investigated. Laser written structures of different aspect ratio (height to width) on a copper surface tuned the SEY of the surface and reduced its value to less than ...

High-performance complementary resistive switching in ferroelectric film

AIP Advances, 2021
The complementary resistive switch (CRS) offers a promising logic-in-memory functionality and is a potential solution to the “von Neumann bottleneck” problem, but the CRS structure composed of two anti-serially connected bipolar resistive switching cells

Multiphoton non-local quantum interference controlled by an undetected photon

Nature Communications, 2023
Usually, observation of quantum interference in a non-local scenario (that is, when Alice’s measurement settings and Bob’s outcomes are space-like separated) relies on entanglement.
