OWLAN Up-Down Link Simultaneously by Optical Spin Generated

Abstract

-This paper proposed a new idea of optical wireless communication simultaneously using the optical spin phenomena. The spin generation from bright and dark soliton conversion behaviors within a modified optical add-drop filter known as PANDA ring resonator is proposed. The orthogonal solitons can be formed within the system and detected simultaneously at the output ports. Under the resonant condition, the dark and bright soliton pair corresponding to the left-hand and right-hand rotating solitons (photons) can be generated. When a soliton 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(soliton) spins are exhibited. The arrays of orthogonal soliton spins can be applied a spin up for uplink and spin down for downlink representation in optical wireless communication.
