Distributed measurement of mode group effective refractive index difference in a few mode optical fibers

Luc Thévenaz, Zhisheng Yang, Alejandro Dominguez Lopez

The possibility to perform distributed measurements of the effective refractive index difference between distinct modes in few mode optical fibers is demonstrated using phase sensitive optical time domain reflectometry. Effective refractive index differenc ...

Frequency scanned phase sensitive optical time-domain reflectometry interrogation in multimode optical fibers

Luc Thévenaz, Zhisheng Yang, Alejandro Dominguez Lopez

Standard multimode optical fibers normally support transmission over some 100 modes. Large differences in the propagation constant and the spatial distribution of distinct modes degrade the performance of phase-sensitive optical time-domain reflectometry m ...

High-resolution distributed shape sensing using phase-sensitive optical time-domain reflectometry and multicore fibers

Luc Thévenaz, Marcelo Alfonso Soto Hernandez, Zhisheng Yang, Alejandro Dominguez Lopez

In this paper, a highly-sensitive distributed shape sensor based on a multicore fiber (MCF) and phase-sensitive optical time-domain reflectometry (φ-OTDR) is proposed and experimentally demonstrated. The implemented system features a high strain sensitivit ...
