“…κ m and κ a are the losses of magnon and microwave cavity modes. Like the computation process of phonon laser [39,41], assuming that the magnon mode is strongly driven, leading to a large amplitude | m | ≫ 1 at the steady state, and due to the cavity-magnon beam splitter interaction, the cavity field also has a large amplitude | a | ≫ 1. That leads to the quantum noise terms can be safely neglected if one is interested only in the mean-number behaviors (i.e., the threshold feature of the mechanical gain or the phonon amplifications).…”

Using phonons to simulate an optical two-level laser action has been the focus of research. We theoretically study phonon laser in a cavity magnomechanical system, which consist of a microwave cavity, a sphere of magnetic material and a uniform external bias magnetic field. This system can realize the phonon-magnon coupling and the cavity photon-magnon coupling via magnetostrictive interaction and magnetic dipole interaction respectively, the magnons are driven directly by a strong microwave field simultaneously. Frist, the intensity of driving magnetic field which can reach the threshold condition of phonon laser is given. Then, we demonstrate that the adjustable external magnetic field can be used as a good control method to the phonon laser. Compared with phonon laser in optomechanical systems, our scheme brings a new degree of freedom of manipulation. Finally, with the experimentally feasible parameters, threshold power in our scheme is close to the case of optomechanical systems. Our study may inspire the field of magnetically controlled phonon lasers.

“…Inspired by the Sagnac effect, however, nonreciprocal optical transmissions can also be realized by spinning a whispering-gallery-mode (WGM) resonator [40,41]. With this technology, nonreciprocal photon blockade [42] and phonon lasing [43] have been achieved in succession. Most recently, Xu et al proposed a nonreciprocal transition scheme of nondegenerate energy levels based on reservoir engineering, which may serve as the kernel of a nonreciprocal singlephoton transporter [44].…”

We study the quantum interference between different weak signals in a three-port optomechanical system, which is achieved by coupling three cavity modes to the same mechanical mode. If one cavity serves as a control port and is perturbed continually by a control signal, nonreciprocal quantum interference can be observed when another signal is injected upon different target ports. In particular, we exhibit frequency-independent perfect blockade induced by the completely destructive interference over the full frequency domain. Moreover, coherent photon routing can be realized by perturbing all ports simultaneously, with which the synthetic signal only outputs from the desired port. We also reveal that the routing scheme can be extended to more-port optomechanical systems. The results in this paper may have potential applications for controlling light transport and quantum information processing.

“…The frequency separation as large as 0.69 GHz has been observed in the YIG microsphere, thus is promising for realizing broadband non‐reciprocal photonic devices. Furthermore, the optical modes in the ferromagnetic microsphere can be modulated by the magnetic field, analogous to electro‐optics and optomechanical systems . It offers an alternative approach for realizing the quantum frequency conversion between microwave and optical photons …”

Non‐reciprocal devices serving as fundamental elements in photonic and microwave circuits have attracted great attention for its applications in both classical and quantum information processing. The spin–orbit coupling (SOC) of light in microstructures shows that the polarization affects and controls the spatial degrees of freedom of light, which could been exploited to break the reciprocity of light transmission. Here, non‐reciprocal light transmission is demonstrated experimentally in high‐quality factor yttrium iron garnet microspheres via photonic SOC and Faraday effect. By applying an magnetic field in the vertical direction of resonator equator, the degeneracy of the clockwise and counter‐clockwise whispering gallery modes are lifted. The non‐reciprocal effect is shown for both polarizations and promises applications including non‐reciprocal photonic devices, magneto‐optic modulators, and magnetometers.
