M. Tomizawa et al., NONLINEAR INFLUENCE ON PM-AM CONVERSION MEASUREMENT OF GROUP-VELOCITYDISPERSION IN OPTICAL FIBERS, Electronics Letters, 30(17), 1994, pp. 1434-1435
The authors propose a method for measuring the group velocity dispersi
on, including the polarity, of optical fibre by using a single wavelen
gth light source. The method is based on the interplay between phase m
odulation-amplitude modulation (PM-AM) conversion and self-phase modul
ation (SPM).
