The orthogonal solitons can be formed randomly within the system and detected simultaneously at the output ports. Under the resonant condition, the orthogonal solitons corresponding to the left-hand and right-hand solitons (photons) can be generated. Whenever a photon is absorbed by an object, an angular momentum of either + _ or - _ is imparted to the object, in which two possible spin states known as soliton spins are exhibited. Many soliton spins, i.e., many particles, dynamic spin and long distance spin transport using the proposed design are also discussed. © 2012 World Scientific Publishing Company.optical spinorthogonal solitonsoliton spinSpin transportReviewScopus
