Coherent Optical Transmission Characteristics Based on Magneto-Optical Force System

A magneto-optical force system including magnon-phonon-photon interaction is proposed, which comprises of a magnon (YIG sphere) and an optical resonator. In this system, the magnons are characterized by the collective motion of the majority of spins in macroscopic ferrimagnet, and coupled with photons via magnetic dipole interaction and with phonons via magneto-strictive interaction, respectively. Based on the rigorous theories of quantum optics and input-output relationship, the coherent optical transmission properties in the proposed system are studied. By controlling the parameters of the system, the output field can be controlled effectively, which provides a promising platform for the study of macroscopic quantum phenomena.
