Fig. 2: Experimental results.
a Tunable storage of a 200 ps-long data pulse for up to 14 ns. The retrieved data is shown in black dotted lines. (The black signal shown with zero delay is the detected residual power of the data pulse that is not converted to the acoustic wave.) Inset: zoom-in from 8 to 14 ns. b Full-width at half-maximum of the retrieved pulses at different storage times, average value: 230 ps. c Read-out of different intensity levels after 2 ns. d Linear dependence of input to output amplitude.
