Optical spin manipulation using dark-bright soliton behaviors in a panda ring resonator

Abstract

A new concept of an optoelectronic spin generation using bright and dark soliton conversion behaviors within a modified optical add‐drop filters known as a PANDA ring resonator is proposed. The orthogonal solitons can be formed randomly within the system and detected simultaneously at the output ports. Under the resonant condition, the random transverse electric and magnetic fields of the solitons corresponding to the left‐hand and right‐hand photons can be generated. Whenever a photon is absorbed by an object, an angular momentum of either + ħ or –ħ is imparted to the object, in which two possible spin states known as optoelectronic spins are exhibited. Furthermore, the array of optoelectronic spins, i.e., many particles can be generated and controlled by using the proposed system, which can be used to form large scale spintronics applications.
