Generation of higher-order sidebands based on the magnetostrictive interaction in a hybrid cavity electro-opto-magnomechanical system

摘要

Magnetostrictive interaction, as a nonlinear effect, provides a great opportunity to establish a tunable cavity magnomechanical system and may bring many interesting physical phenomena and potential applications. Here, we theoretically investigate the generation and control of higher-order sideband phenomena in a hybrid cavity electro-opto-magnomechanical system, in which the geometrical deformation of yttrium iron garnet can be treated as an excellent mechanical resonator. We show that the amplitude of the sideband can be considerably enhanced in the case of blue detuning of the microwave cavity field, and we also find an interesting pump-field-detuning-controlled optical switch effect. Furthermore, numerical calculations of the system's dynamic equations show excellent agreement with our analytical results. Our results will contribute to the understanding of nonlinear coherent phenomena and have the potential to greatly advance the fields of cavity electro-opto-magnomechanical systems and nonlinear optics.
