  Since the first experimental observation of optical Airy beams, various
applications ranging from particle and cell micromanipulation to laser
micromachining have exploited their non-diffracting and accelerating
properties. The later discovery that Airy beams can self-heal after being
blocked by an obstacle further proved their robustness to propagate under
scattering and disordered environment. Here, we report the generation of Airy
beams on an integrated silicon photonic chip and demonstrate that the on-chip
1D Airy beams preserve the same properties as the 2D beams. The 1D meta-optics
used to create the Airy beam has the size of only 3 by 16 microns, at least
three orders of magnitude smaller than the conventional optic. The on-chip
self-healing beams demonstrated here could potentially enable diffraction-free
light routing for on-chip optical networks and high-precision micromanipulation
of bio-molecules on an integrated photonic chip.
