Optimized shaping of stored data-pulse by stimulated Brillouin scattering in an optical fiber

The effect of a proper shaping of the temporal envelope of stored data-pulse based on stimulated Brillouin scattering in As2Se3 optical fibers is studied. The stored data-pulse shape can be optimized to lead to a substantial enhancement of the readout efficiency and reduction of aberration of the data-pulse. The spectrum of the three different data-pulses is engineered so that the spectral width of the pulses is changed while preserve the pulse duration, making possible to match at best the control pulse spectrum. Gaussian shaped pulses show the optimized temporal profile gain the biggest readout efficiency and the smallest aberration when compared to exponential and rectangular pulses.
