    In this paper, we present the controllable four-wave mixing (FWM) within PANDA ring resonator based-on optical soliton manipulation. After a dark soliton pulse is fed into an input port of the resonator, the FWM can be formed within the system and detected simultaneously at the output ports. Under the resonant condition, the FWM can be controlled by adding Gaussian or bright soliton at the add port. Whenever a soliton(photon) is absorbed by an object, an angular momentum of either + h or -h is imparted to the object, in which two possible soliton states known as soliton spins are seen. In application, the controllable FWM can be used atom/photon manipulation. © 2010 Published by Elsevier Ltd.
