Experimental study shows Bragg scattering of wave packets, suggesting boundaries may be modified.
Here we report the experimental observation of Bragg scattering of a wave packet with a space-time Bragg grating. By tuning the grating unit size, the continuous space-time boundary condition can be partially or fully broken.
