Methods for the enhancement of the storage time in quasi-light-storage

Abstract

The Quasi-Light-Storage (QLS) is a method for the variable and almost distortion free storage of optical data which is based on the filtering of the spectra with stimulated Brillouin scattering (SBS). The natural gain bandwidth of SBS limits the storage time of this method to 100 ns. We overcome this limitation by using a narrowed gain for the SBS and a fiber loop, respectively.
