Complete Mode Spectrum Decomposition of Complex‐Structured Light by Computer‐Generated Holography
Advanced Photonics Research, Volume 6, Issue 2, February 2025.In this article, a new optical method based on self‐interference is proposed to completely decompose the eigenmode spectrum of complex‐structured light. A diffractive optical method is designed and validated to extract the complete information of complex‐structured light fields composed with eigenmode superposition states, including the order of ...

Two-mode squeezed vacuum and squeezed light in correlated interferometry [PDF]
Phys. Rev. A 92, 053821 (2015), 2015 We study in detail a system of two interferometers aimed to the detection of extremely faint phase-fluctuations. This system can represent a breakthrough for detecting a faint correlated signal that would remain otherwise undetectable even using the most sensitive individual interferometric devices, that are limited by the shot noise.

Quantification of Interfacial Charges in Multilayered Nanocapacitors by Operando Electron Holography
Advanced Materials, Volume 37, Issue 4, January 29, 2025.Operando off‐axis electron holography is used to quantify the charges trapped at the dielectric/dielectric interfaces and metal/dielectric interfaces in HfO2‐ and Al2O3‐based nanocapacitors. The electrostatic potential maps, recorded with a sub‐nanometer spatial resolution while applying a bias, demonstrate that these interfaces present a high density ...
