腔磁力系统中的诱导透明和快慢光传播

为了在腔磁力系统中实现可控的磁子诱导透明、磁力诱导透明以及快慢光传播,建立了一个混合腔磁力系统.该系统由一个含有YIG球的微波腔和在z方向对球施加一个均匀的偏置磁场组成,并用强泵浦场驱动磁子和弱探测场驱动微波腔.研究表明,通过调节腔与磁子之间的相互作用强度和微波腔与磁子的耗散比,可以增加磁子诱导透明(MIT)、磁力诱导透明(MMIT)的效果和提高快慢光传播的速度.该研究结果可为磁力诱导放大、量子光学操纵和量子信息存储以及灵敏光开关的研究提供参考.

Induced transparency and fast-slow light propagation in a hybrid cavity magnomechanical system

In order to realize controllable magnon - induced transparency, magnomechanical - induced transparency and fast - slow light propagation, a hybrid cavity magnomechanical system is established.In this system, a YIG sphere is placed in the microwave cavity, and a uniform bias magnetic field is applied on the sphere in z direction.A strong pump field is used to drive the magnon while a weak probe field is used to drive the microwave cavity.By adjusting the strengths of interaction between cavity - magnon and the dissipation ratio between microwave cavity and magnon can enhance the effect of magnon - induced transparency(MIT), magnomechanical - induced transparency(MMIT)and improve the propagation speed of fast - slow light.This system can provide reference for magnomechanical - induced amplification, quantum optical manipulation, quantum information storage and sensitive optical switching.
