Fully Distributed Fiber-Optic Sensing Enabled by Kalman Filtering
Juan M. Marin, Roman Ermakov, Florian Azendorf +4
Signal fading creates points along the fiber where phase cannot be extracted, so they are conventionally discarded. Instead, we propose a Kalman-based solution for ϕ-OTDR full-fibe…

Beyond white- and black-box modeling tools in optical communications and optical computing: physics-informed data-driven modeling
Isidora Teofilovic, Sergio Hernandez Fernandez, Metodi P. Yankov +3
Efficient optimization and control of photonic computing and communication systems increasingly rely on accurate surrogate models/digital twins. While data-driven models may achiev…

Phase Noise Characterization of Cr:ZnS Frequency Comb using Subspace Tracking
Aleksandr Razumov, Sergey Vasilyev, Mike Mirov +4
We present a comprehensive phase noise characterization of a mid-IR Cr:ZnS frequency comb. Despite their emergence as a platform for high-resolution dual-comb spectroscopy, detaile…
