Novel technique for measurement of wavelength of zero relative delay between modes of a dual-mode optical fibre
A simple method of determining the wavelength of zero relative time-delay between the LP01 and LP11 modes of short lengths of a dual-mode optical fibre is described. The measurement allows easy comparison of short and long lengths of fibre. The technique may prove to be more convenient and reliable than those presently used for characterising monomode fibres.
