Abstract
A study that combines experimental measurements of the effects of a focused laser beam on the current-voltage characteristics and computer simulations of Josephson tunnel junctions shows that there are different dynamic modes which are responsible for the zero-field current steps at finite voltages. One of the modes is associated with the soliton-antisoliton propagation. The dc tunneling current in this case is found to be predominantly the zero-voltage pair current flowing near the junction edges. The other mode can be attributed to the standing-wave excitations of electromagnetic waves. The dc tunneling current of this mode is spatially oscillatory.
