Abstract
Long Josephson junctions are very attractive non-linear systems where solitonic dynamics [14] is fully developed and directly related to experimentally observable quantities. In this system the soliton occurs as a solution of the sine-Gordon equation describing the long junction; physically, it represents a fluxon, a current vortex enclosing a flux quantum. Coherent motion of fluxons is an intriguing subject, also because of its possible practical applications. In fact, microwave and far infrared fluxon oscillators [15] greatly enhance their performances if such a motion is established. Here we will consider three different coupled structures of long Josephson junctions where coherent fluxon motion is experimentally demonstrated.
