Abstract

We propose to achieve a multicolor nonreciprocal optical amplifier, a crucial device in optical communication and information processing, by spinning an active resonator. We show that in such a device, due to the interplay of the Sagnac effect and the optical gain, nonreciprocal signal amplification can be realized, accompanied by a giant enhancement of optical group delay from $0.3\phantom{\rule{0.28em}{0ex}}\mathrm{ms}$ to $35\phantom{\rule{0.28em}{0ex}}\mathrm{ms}$ in a chosen direction, which is otherwise unattainable in a passive device. Also, coherent amplification of higher-order optical sidebands and a slow-to-fast light switch can be achieved by tuning both the pump power and the spinning velocity. Our work provides a unique and accessible way, well compatible with other existing techniques, to realize multicolor nonreciprocal optical amplifiers for more flexible control of optical fields.

Nonreciprocal photonic transistor with a spinning polaritonic microcavity

Zi-Fa Yu, Pengfei Yan, Ji-Ming Gao +4 more

We propose a theoretical scheme to achieve a nonreciprocal polaritonic photonic transistor by using a spinning microresonator coupled to a tapered fiber. In such a nonreciprocal device, owing to the combination of Sagnac effects and Stokes or anti-Stokes scattering, the transmission of probe light in clockwise and counterclockwise directions exhibits clockwise (counterclockwise) unidirectional amplification, bidirectional amplification, and bidirectional attenuation, simultaneously accompanied by unidirectional slow-fast light, bidirectional fast light, and bidirectional slow light, which can be effectively modulated by pump fields and couplings among excitons, photons, and phonons. In particular, we also discover perfect unidirectional transmission, i.e., the transmission in the opposite direction is completely blocked, and fast-slow light switching by appropriately regulating pump fields, which is optimal for signal isolation and controllable group advance-delay switching. Therefore, our proposed nonreciprocal photonic transistor is an excellent multifunctional device with various amplification-attenuation transmission and fast-slow light nonreciprocities. Our results provide an opportunity to engineer multifunctional nonreciprocal photonic devices, which may be useful for building integrated photonic circuits, chiral quantum technologies, and quantum communication networks.

Directional amplifier in an optomechanical system with optical gain

Cheng Jiang, Lijia Song, Yong Li

Directional amplifiers are crucial nonreciprocal devices in both classical and quantum information processing. Here we propose a scheme for realizing a directional amplifier between optical and microwave fields based on an optomechanical system with optical gain, where an active optical cavity and two passive microwave cavities are coupled to a common mechanical resonator via radiation pressure. The two passive cavities are coupled via hopping interaction to facilitate the directional amplification between the active and passive cavities. We obtain the condition of achieving optical directional amplification and find that the direction of amplification can be controlled by the phase differences between the effective optomechanical couplings. The effects of the gain rate of the active cavity and the effective coupling strengths on the maximum gain of the amplifier are discussed. We show that the noise added to this amplifier can be greatly suppressed in the large cooperativity limit.

Squeezing-induced nonreciprocal transparency and the slow-to-fast-light switch

Deng Wang, Yin Bin, Jie Wang +4 more

We propose a theoretical method to realize nonreciprocal light transmission in an optomechanical device assisted by directional quantum squeezing. Specifically, we consider the device consisting of an optomechanical resonator and a nonlinear optical resonator with directional pumping. We find that optical squeezing occurs along the pump direction when the nonlinear resonator is directionally pumped, enabling nonreciprocal light transmission as well as nonreciprocal group delay (slow light) or advancement (fast light). Furthermore, we find that the efficiency of the second-order sidebands can be enhanced in one direction compared with the opposite direction. Our work provides a promising design for the application of directionally squeezed optomechanical devices in nonreciprocal optical communication and signal processing.

Dual-gate transistor amplifier in a multimode optomechanical system

Yao-Tong Chen, Lei Du, Yi-Mou Liu +1 more

We present a dual-gate optical transistor based on a multimode optomechanical system, composed of three indirectly coupled cavities and an intermediate mechanical resonator pumped by a frequency-matched field. In this system, two cavities driven on the red mechanical sidebands are regarded as input/ouput gates/poles and the third one on the blue sideband as a basic/control gate/pole, while the resonator as the other basic/control gate/pole. As a nonreciprocal scheme, the significant unidirectional amplification can be resulted by controlling the two control gates/poles. In particular, the nonreciprocal direction of the optical amplification/rectification can be controlled by adjusting the phase differences between two red-sideband driving fields (the pumping and probe fields). Meanwhile, the narrow window that can be analyzed by the effective mechanical damping rate, arises from the extra blue-sideband cavity. Moreover, the tunable slow/fast light effect can be observed, i.e, the group velocity of the unidirectional transmission can be controlled, and thus the switching scheme of slow/fast light effect can also utilized to realize both slow and fast lights through opposite propagation directions, respectively. Such an amplification transistor scheme of controllable amplitude, direction and velocity may imply exciting opportunities for potential applications in photon networks and quantum information processing.

Switching classical and quantum nonreciprocities with spinning photonics

Yonglin Xiang, Yunlan Zuo, Xun‐Wei Xu +2 more

We study how to achieve, manipulate, and switch classical or quantum nonreciprocal effects of light with a spinning Kerr resonator. In particular, we show that even when there is no classical nonreciprocity (i.e., with the same mean number of photons for both clockwise and counterclockwise propagating modes), it is still possible to realize nonreciprocity of quantum correlations of photons in such a device. Also, by tuning the angular velocity and the optical backscattering strength, higher-order quantum nonreciprocity can appear, featuring qualitatively different third-order optical correlations, even in the absence of any nonreciprocity for both the mean photon number and its second-order correlations. The possibility to switch a single device between a classical isolator and a purely quantum directional system can provide more functions for nonreciprocal materials and new opportunities to realize novel quantum effects and applications, such as nonreciprocal multi-photon blockade, one-way photon bundles, and backaction-immune quantum communications.

Backscattering-Immune Nonreciprocal Optical Solitons in a Spinning Resonator

Bai‐Jun Li, Şahin Kaya Özdemir, Xun‐Wei Xu +2 more

We show that nonreciprocal optical solitons that are immune to backscattering-induced losses appear in a spinning optical Kerr resonator. Nonreciprocity in this device results from the Sagnac-Fiezau drag effect, which is different for pump fields propagating in the spinning direction or in the direction opposite to it. We find that these nonreciprocal solitons are more robust against backscattering losses if the spinning speed of the resonator is properly set. Our work represents a stable nonreciprocal soliton device and provides a promising technique for one-way soliton isolators and lasers, backaction-immmune soliton communication, and enhanced soliton-comb metrology.
