Manipulation of soliton ensembles by spectral filters

It was shown recently that an ensemble of solitons can be created in a driv en optical fiber resonator. The ensemble can exist in either an ordered or a disordered state; these have been referred to as soliton solid or gas (fl uid), respectively. We demonstrate through numerical simulation that the tr ansition from one state to the other or vice versa, and further manipulatio n of the ensemble, can be effected through the insertion of spectral filter s.
