PIDT: Physics-Informed Digital Twin for Optical Fiber Parameter Estimation
arXiv:2601.07436 · doi:10.1364/OFC.2026.M4K.3
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.
