  1. Fig. 1.

    Storage of data pulses as an acoustic disturbance in an optical fiber and their subsequent retrieval after a controllable time interval. In the storage process, a short, intense write pulse that is detuned to the low-frequency side of the data-pulse frequency by the Brillouin frequency shift causes the data pulses to become depleted (A) with the information being stored as an acoustic wave in the medium (B). In the retrieval process (C), a short, intense read pulse at the same frequency as the write pulse depletes the acoustic wave and converts the data back to the original optical frequency, thereby producing a replica of the incident data pulses (D).

  2. Fig. 2.

    Observation of stored light. (A) shows experimental results for a 2-ns-long rectangular-shaped data pulse, and (C) shows the corresponding theoretical simulations. (B) shows the case of a 2-ns-long smooth data pulse, with the corresponding simulations shown in (D). The retrieved pulses are shown with a multiplication factor of 2 to the right of the dashed vertical line.

  3. Fig. 3.

    Storage of pulse sequences. (A) shows experimental results for two 2-ns-long data pulses separated by 1 ns, and (C) shows the corresponding theoretical simulations. (B) shows the case of three 2-ns-long data pulses separated by 1 ns, with the corresponding simulations shown in (D). The retrieved pulses are shown with a multiplication factor of 5 to the right of the dashed vertical line. For clarity, the depleted data pulses are not shown.
