All‐Fiber Microsensor of Polarization at Single‐Photon Level Aided by Deep Learning (Laser Photonics Rev. 20(3)/2026)
Abstract
From Disorder to Knowledge To harness deep learning to recover polarization information from the chaotic speckle created by a short piece of a few-mode fiber, Miroslav Ježek and co-workers have built an all-fiber, AI-assisted sensor that reconstructs complete polarization states at single-photon levels. Their work, presented in Research Article e01775, demonstrated high-speed polarization sensing with unprecedented accuracy for diagnostic applications in material and biomedical research.
