We demonstrate theoretically that chirped dynamic gratings can be created in optical fibers through stimulated Brillouin scattering with frequency-chirped "signal" and "write" pulses. When the grating is interrogated with a third pulse of the opposite chirp, a compressed signal pulse is retrieved. This provides a method to regenerate stored pulses and enhance signal levels for communications applications.
我们从理论上证明,通过受激布里渊散射,利用频率啁啾的“信号”和“写入”脉冲,可以在光纤中产生啁啾动态光栅。当用具有相反啁啾的第三个脉冲对光栅进行询问时,可恢复一个压缩的信号脉冲。这为通信应用提供了一种再生存储脉冲并提高信号电平的方法。
