Experimental results of all-optical tunable buffering. (a) Signal output for different control pulse widths τ width,c. The blue and grey solid lines represent the signal output and input, respectively. The time width of the input signal pulse is 10 ns. The pulse widths and the peak powers of the control pulses (τ width,c, P in,c) are (5 ns, 15.1 W), (10 ns, 13 W), (15 ns, 8.4 W), and (20 ns, 7.3 W), respectively. The control pulse is input in the red region. (b) Enlargement of (a). (c) The peak power of the buffered signal pulse as a function of the control pulse width. The blue rectangles and red dashed lines plot the measured and calculated results, respectively. The same parameters used in Fig. 2(b,c) were employed for the calculation. y axis is normalized by the peak power of the input signal pulse.
