Abstract
Chiral interaction between light and quantum emitters leads to emergence development of chiral quantum optics and stimulates a wide range of practical applications in quantum regime, such as single-photon isolation and photon unidirectional emission. Cavity optomechanics studying the interaction between optical and mechanical resonators plays an important role in the field of quantum optics. However, how to achieve the chiral interaction between light and mechanical oscillators and explore the applications of the chiral optomechanical systems are still difficult encountered in cavity optomechanics. Here, a method is proposed to achieve chiral optomechanical interaction by exploiting directional squeezed light in a multimode optomechanical system. Based on the chiral interaction between photon and phonon, the nonreciprocal photon transport at a single-photon level can be realized. An isolation ratio of and a negligible insertion loss for the photonic isolator are obtained. This method paves the way to realize chiral optomechanical interaction for conducting chiral optomechanics and opens up the prospect of exploring and utilizing chiral photon–phonon manipulation in the quantum regime.
光与量子发射器之间的手性相互作用导致了手性量子光学的出现和发展,并激发了量子领域的广泛实际应用,如单光子隔离和光子单向发射。研究光学和机械谐振器之间相互作用的腔体光机械学在量子光学领域发挥着重要作用。然而,如何实现光与机械振子之间的手性相互作用,探索手性光机械系统的应用,仍然是腔体光机械学中遇到的难题。本文提出了一种在多模光机械系统中利用定向挤压光实现手性光机械相互作用的方法。基于光子和声子之间的手性相互作用,可以实现单光子水平的非互惠光子传输。光子隔离器的隔离比为 40 dB ${>}40\\text{dB}$ ,插入损耗可忽略不计。该方法为实现手性光机械相互作用以开展手性光机械学铺平了道路,并为探索和利用量子体系中的手性光子-声子操纵开辟了前景。
