Accurate calibration of S2 and interferometry based multimode fiber characterization techniques

Accurate calibration of S2 and interferometry based multimode fiber characterization techniques
We present a novel method to validate the relative amount of power carried by high order modes in a multimode fiber using a Spatial and Spectral (S2) imaging technique. The method can be utilized to calibrate the S2 set-up and uses Fresnel reflections from a thin glass plate to compare theoretical values with experimental results. We have found that, in the most general case, spectral leakage and sampling errors can lead S2 to underestimate the multipath interference (MPI) of high order modes by several decibels, thus significantly impairing the result of the measurement. On the other hand, by applying suitable corrections as described in this work, we demonstrate that the S2 produces MPI estimates that are accurate to within 1dB or better.

Abstract

We present a novel method to validate the relative amount of power carried by high order modes in a multimode fiber using a Spatial and Spectral (S2) imaging technique. The method can be utilized to calibrate the S2 set-up and uses Fresnel reflections from a thin glass plate to compare theoretical values with experimental results. We have found that, in the most general case, spectral leakage and sampling errors can lead S2 to underestimate the multipath interference (MPI) of high order modes by several decibels, thus significantly impairing the result of the measurement. On the other hand, by applying suitable corrections as described in this work, we demonstrate that the S2 produces MPI estimates that are accurate to within 1dB or better.
