Abstract
Soliton molecules, exhibiting similarities to molecular-like behavior, have attracted tremendous attention. With the dramatic recent advances in real time spectroscopic techniques as well as time-domain probes, the detailed nature of various soliton molecular has been revealed. Particularly, time-stretch dispersive Fourier transform (DFT) technique has been applied to unveil the complex internal dynamics of bound states. Nevertheless, the observation time frame of such technique is limited to hundreds of micro seconds mainly confined by the storage capability of the real time oscilloscopes, as well as by the number and the distribution of soliton pulses. Here, we experimentally demonstrate a new probing concept, orbital angular momentum (OAM)-resolved method, for visual extraction of long-term internal phase motions within soliton molecules produced by a mode locked laser.
