Dispersion Measurement with Optical Computing Optical Coherence Tomography

We propose a novel technique to measure fiber dispersion without any derivative operation and index measurement. Based on the relationship between the dispersion and the signal in optical computing optical coherence tomography, dispersion can be deduced with high accuracy from optical computing OCT signal position and resolution. The group velocity dispersion and third order dispersion of single mode fiber and dispersion compensating fiber with lengths of 10 m-10 km are measured to be in good consistence with the nominal value.

Automated summary

In this paper, we propose a novel technique to measure fiber dispersion without the need for any derivative operation or index measurement. By utilizing the relationship between dispersion and the signal in optical computing optical coherence tomography, dispersion can be accurately deduced from the position and resolution of the optical computing OCT signal. The measured group velocity dispersion and third order dispersion of single mode fiber and dispersion compensating fiber with lengths ranging from 10 m to 10 km are found to be in good agreement with the nominal value.
