Experimental demonstration of intermodal dispersion in a two-core optical fiber

By K.S. Chiang, Y.T. Chow, D.J. Richardson, D. Taverner, L. Dong and L. Reekie


The recent prediction that intermodal dispersion can play a significant role in pulse evolution in a two-core optical fiber was confirmed experimentally. A picosecond pulse at 1.548µm launched into one core of a meters-long two-core fiber was found to come out of either core of the fiber as two temporally separate pulses. By measuring the time delay between these two pulses, the intermodal dispersion in the fiber was estimated to be 1.13ps/m, in good agreement with theory
