Magnomechanically induced sum sideband generation in multi-field-driven cavity magnomechanics

Nonlinear frequency generation, which involves the creation of new frequency components through nonlinear interactions between light waves within nonlinear optical media, holds significant relevance in various fields including laser physics, optical communications, and optical sensing. Similar to sum frequency generation, the sum sideband generation is discussed in this work. The cavity magnomechanical system is driven by the microwave pumping field (strong control field), the sum sideband can be induced under the drive of two probe fields by utilizing the nonlinear magnon-phonon interaction, namely the magnetostrictive effect. And, the efficiency of sum sideband generation can be enhanced by increasing the power of the control field. Furthermore, the sum sideband can be induced to generate under different matching conditions by adjusting the detuning between the two probe fields and the control field. These results are contribute to the understanding of the nonlinear magnon-phonon interaction, and hold potential applications in quantum precision measurement.
