Magnon-mediated optical frequency comb in a cavity optomagnonical system

Year: 2024

Type: article

Abstract: Generally, optical frequency combs (OFC) are generated through nonlinear effects in optical pumping, such as Kerr nonlinearity, the electro-optic effect, and second-order nonlinearity. Here, we propose an effective mechanism for generating OFC in a cavity optomagnonical system via the nonlinearity of magnon-photon coupling. Our results demonstrate that robust OFC can be achieved in this system when driven by effective nanosecond pulses in the non-perturbation regime. Notably, the addition of an extra microwave pump field can enhance magnon-photon coupling and reduce the system’s reliance on the optical pump field. Furthermore, the number and spacing of the OFC teeth can be adjusted by selecting appropriate experimental parameters. These findings contribute to a deeper understanding of the quantum and nonlinear properties of magnons and pave the way for the development of OFC devices in integrated optics and photonics.
