Photon-Echoes in a Pumped Er-Doped Fiber
Valéria Loureiro da Silva, Yaron R. Silberberg
Recently we reported the first photon echo experiments in Er-doped fibers, and described their application to ultrafast time domain signal processing [1]. Our previous results were obtained with absorbing Er-doped fibers at 4°K, and our signals at 1.53µm were attenuated by the fiber. In this paper we report photon echo experiments with Er-doped amplifiers. We expect the photon echo process in amplifiers to yield strong echoes, perhaps stronger then the input signal. This could be important for signal processing applications. To our knowledge this is the first demonstration of photon echo in any inverted system.
