Phase-sensitive optical low-coherence reflectometry technique applied to the characterization of photonic crystal fiber properties

Opt Lett. 2005 Feb 15;30(4):361-3. doi: 10.1364/ol.30.000361.

Abstract

Localized measurements of group-velocity dispersion and birefringence of photonic crystal fibers are achieved with a phase-sensitive optical low-coherence reflectometry technique. This technique is efficient for fiber samples no longer than 1 m. Theoretical simulations are in good agreement with experimental results. As a result, the stress-induced birefringence proves to be at most 1 order of magnitude below the geometrical-shape birefringence.
