Theoretical analysis and measurement of effectsof fibre twiston polarisation mode dispersion of optical fibres

Abstract

The authors present an analytical model of the polarisation mode dispersion (PMD) of uniform linearly birefringent fibres subject to elastic twist which shows there exists a particular twist rate which nulls the PMD. At high twist rates, the PMD is dominated by the dispersion of the twist-induced circular birefringence. Experimental results confirm the predictions.
