Overview

A novel framework constructs a deformation-resolved modal basis in multimode fibers, supporting sensing applications and network resilience.

Key Points

  • The method captures the optical response across a range of mechanical deformations, enabling detailed analysis of fiber conditions.
  • Using a two-stage singular value decomposition, it builds a comprehensive modal basis from speckle pattern correlations, enhancing accuracy.
  • This approach supports robust tracking of deformation-induced changes, which is critical for distributed sensing applications.
  • The hierarchical framework allows for integration into mode-division multiplexing systems, enhancing network resilience and fault diagnostics.
