Abstract
Pulse dispersions as low as 0.4 ns/km have been measured in multimode cladded fibres at a normalised frequency V=125 and for a constant bend radius of 5.5 cm. Particularly when the number of launched modes is small, the pulse dispersion, as well as the polarisation and angular width of the output beam, are strong functions of the degree of mode conversion.Keywords
