We demonstrate a memory for light based on optomechanically induced transparency. We achieve a long storage time by leveraging the ultralow dissipation of a soft-clamped mechanical membrane resonator, which oscillates at MHz frequencies. At room temperature, we demonstrate a lifetime T_{1}≈23 ms and a retrieval efficiency η≈40% for classical coherent pulses. We anticipate the storage of quantum light to be possible at moderate cryogenic conditions (T≈10 K). Such systems could find applications in emerging quantum networks, where they can serve as long-lived optical quantum memories by storing optical information in a phononic mode.
我们展示了基于光机械诱导透明的光存储。通过利用在兆赫兹频率下振荡的软夹持机械膜谐振器的超低损耗，我们实现了较长的存储时间。在室温下，对于经典相干脉冲，我们展示了寿命(T_{1}\approx23)毫秒和检索效率(\eta\approx40%)。我们预计在中等低温条件（(T\approx10)开尔文）下存储量子光是可行的。此类系统可在新兴的量子网络中找到应用，在其中它们可通过将光信息存储在声子模式中作为长寿命光学量子存储器。
