Fig. 1. (a) Schematic of the experiment setup. (b) Measured spectra of an Airy pulse (green) and a signal (cyan), trimmed from a femtosecond laser pulse of a broad band (red), where the vertical dashed line marks the zero-dispersion wavelength (ZDW). The inset shows the relative group delay of the DSF we used in experiment. (c) Experimental measurement (black) and numerical simulation (blue) of the input profiles of an Airy pulse with a=−0.5  ps3.

Fig. 2. Trapping and guiding of a weak signal pulse of Gaussian-like shape via a nonlinear Airy pulse. (a) Experimental measurements of the wavelength conversion for the signal with different initial time delays. (b) Numerical simulations corresponding to (a). (c)–(f) Simulations of propagation dynamics for (c) the Airy pulse and (d)–(f) the signal pulse corresponding to three different initial time delays marked by D, E, F in (b) and (c). The white dotted lines in (c)–(f) are added to trace the main lobe of the Airy pulse.

Fig. 3. Spectral (upper row) and temporal (bottom row) outputs of the signals with different input pulse durations. (a) Experimental measurements in the presence of the Airy pulse. (b)–(d) Numerical simulations using the experimental parameters associated with (a), but in (d) the Airy pulse is assumed to be absent.

Fig. 4. Experimental measurements (left column) and numerical simulations (right column) on the control of the signal guiding by using reconfigurable accelerating potentials. Upper row has the same description with Figs. 2(a) and 2(b) but with an opposite acceleration sign. Bottom row shows the output spectra of the signal pulse driven by the control pulse of different accelerations while keeping near-zero time delay of signal.

Fig. 5. Guiding and routing a double-peak signal via an accelerating potential. (a) Simulated signal propagation in the presence of the Airy pulse shown in Fig. 2(c). (b) and (c) Spectral input and output obtained from both simulation and experiment corresponding to (a), respectively. (d) Output spectrum for a deteriorated guiding of the double-peak signal under inappropriate input conditions.

Fig. 6. (a) Potential (blue curve) induced by the Airy pulse in the accelerating frame, and the plateau in orange is artificially introduced. (b) Fundamental (upper panel) and the second-order (bottom panel) modes associated with the AP in (a). (c) and (d) Propagation of the two modes in (b) under the action of the Airy pulse in the laboratory coordinate, where the white dotted lines trace the accelerating potential.
