ALL-OPTICAL STORAGE OF A PICOSECOND-PULSE PACKET USING PARAMETRIC AMPLIFICATION

We demonstrate all-optical storage of a picosecond-pulse packet of one s and zeros in a fiber buffer in which loss is compensated by parametr ic amplification. An all-fiber phase-sensitive parametric amplifier, w hich exploits a nonlinear Sagnac loop made of standard polarization-ma intaining fiber to provide gain, regenerates the stored pulses on each round-trip. Storage for periods of time up to 1 ms has been observed. Data packets of 10's of kilobits could be stored in this device with use of a higher repetition-rate pump source.
