PIDT: Physics-Informed Digital Twin for Optical Fiber Parameter Estimation

Published 12 Jan 2026 in eess.SP, cs.LG, and physics.optics | (2601.07436v1)

Abstract: We propose physics-informed digital twin (PIDT): a fiber parameter estimation approach that combines a parameterized split-step method with a physics-informed loss. PIDT improves accuracy and convergence speed with lower complexity compared to previous neural operators.
