Abstract

The quasi-light-storage (QLS) is a method for the variable and almost distortion free storage of optical data which is based on stimulated Brillouin scattering (SBS). The natural gain bandwidth of SBS limits the storage time of this method to up to 100 ns. We overcome this limit by the superposition of the SBS gain bandwidth with two losses. With this narrowed gain bandwidth, we were able to enhance the storage time for the QLS by 40%.

摘要

准光存储（QLS）是一种基于受激布里渊散射（SBS）的用于可变且几乎无失真地存储光学数据的方法。SBS的自然增益带宽将该方法的存储时间限制在最长100纳秒。我们通过将SBS增益带宽与两种损耗叠加来克服这一限制。通过这种变窄的增益带宽，我们能够将QLS的存储时间提高40%。
