摘要
Optical memories can be categorized into three regimes,including the optical data storage that use light as a tool to store classical bit values[1,2],coherent memories for light which preserve the amplitude and the phase information of input optical pulses[3,4]and optical quantum memories that specifically work for quantum light field[5,6].Recently,Bland-Hawthorn et al.[7]proposed to construct long-baseline optical telescopes based on transportable optical memories.
光是现代信息传输的基本载体.长寿命的光存储既具有基础物理方面的价值,也在光信息处理领域具有广泛的应用.本文提出一种新型的光存储方案:自旋锁定受激光子回波(简称SLSE).基于该方案,作者在掺铕硅酸钇(Eu:YSO)晶体中实现了可移动的长寿命相干光存储器.存储器及其配套设备实现整体封装并放置在一个电控导轨上往返搬运.在1 h的存储时间里,存储器及其存储的轨道角动量编码光场共被搬运了24 m的距离.结合带宽压缩等量子光学技术,可移动相干光存储器可应用于构建甚长基线光学干涉望远镜.作为一种光传输的新媒介,可移动相干光存储有望进一步催生出更多新的应用.
