“…[35] In 2022, Zhou et al have studied nonreciprocal optical transmission in a spinning resonator system coupled to an atomic ensemble. [40] The aforementioned investigations mainly focused on transmission characteristics, whereas optical devices based on the mechanism of unidirectional reflectionlessness (UR) [41][42][43] can not only protect upper stage optical devices from reflected light in the cascade circuit to improve system stability, but also convey information, similar to transmission. Up to now, UR has demonstrated the significant potential applications in sensors, diodes, isolators, filters, and so on, and thus research on UR continues to grow.…”

The reflection and transmission characteristics of a system composed of two whispering‐gallery mode (WGM) resonators are explored. Each resonator contains a Zeeman split quantum dot and side‐couples to an optical fiber. The results indicate that the unidirectional reflectionlessness and transmissionlessness can be achieved by adjusting the coupling strength between the resonators and the optical fiber, as well as the transition rate between the counter‐propagating modes within the WGM resonators. Besides, a one‐to‐one correspondence is set up between the resonance frequencies of quantum dots' energy levels and the positions of reflectionlessness (transmissionlessness) peaks when phase shift between two WGM resonators is π. This research provides the valuable insights for the development of quantum optical devices such as isolators, circulators, and routers.

“…It is worth noting that spinning resonators may open up a new alternative way to achieve nonreciprocal transmission [37,38] by utilizing the Sagnac effect, which leads to the light circulating in the resonator experiencing an opposite Sagnac-Fizeau shift [39]. Subsequently, several nonreciprocal phenomena related to the Sagnac effect have been deeply explored in spinning resonators, including optical nonreciprocity [40][41][42][43], nonreciprocal photon blockade [38,[44][45][46][47][48], nonreciprocal phonon blockade [49], nonreciprocal phonon laser [50][51][52], nonreciprocal magnon laser [53], nonreciprocal quantum entanglement [54][55][56], and nonreciprocal chaos [57].…”

Nonreciprocity Steered with a Spinning Resonator

An approach is presented to study the controllable nonreciprocal transmission in a spinning resonator. It has been demonstrated in optomechanics that an optical signal field can only be affected when it propagates in the same direction as the driving field. We show that such an optomechanically induced nonreciprocity can be controlled by rotating the resonator, which introduces a frequency shift with different signs for clockwise and counterclockwise optical fields in the resonator. In our scheme, the transmission probabilities of the clockwise and counterclockwise input signal fields can be reversed by tuning the rotation velocity of the resonator. By studying the transmission spectra of the signal field, we also reveal that the nonreciprocity response can be realized in the spinning resonators in the absence of optomechanical coupling, which extends its utility.

Classical and quantum nonreciprocity have important applications in information processing due to their special one-way controllability for physical systems. In this paper we investigate the nonreciprocal transmission and quantum correlation by introducing the dissipative coupling into a linear coupling system consisting of two microdisk resonators. Our research results demonstrate that even in the case of a stationary resonator, dissipative coupling can effectively induce nonreciprocity within the system. Moreover, the degree of nonreciprocity increases with the dissipative coupling strength. Importantly, the phase shift between the dissipative coupling and coherent coupling serves as a critical factor for controlling both nonreciprocal transmision and one-way quantum steering. Consequently, the introduction of dissipative coupling not only enhances the nonreciprocal transmission and nonreciprocal quantum correlation but also enables on-demand manipulation of nonreciprocity. This highlights dissipation as an effective means for manipulating classical and quantum nonreciprocity, thus playing a favorable role in chiral quantum networks.
