  Waveguide arrays have a wide range of applications, including optical
communication, topological systems, and quantum computing. Chiral transport has
broad prospects in optical computing, optical switching, optical isolation, and
polarization control. However, the lengths of chiral transmission devices in
waveguide arrays are typically very long due to adiabatic limit. We introduce
topological protection in encircling exceptional points systems, enabling the
larger gap size between the bulk states and topological edge states (TESs).
Thus, the restriction from adiabatic limit on the rapid evolution of TESs is
eased, thereby significantly reducing the device size. We experimentally
demonstrate that the chiral transport has been achieved in a topological
waveguide array that is only 75 {\mu}m long. Our research fuses the topology
with non-Hermitian physics to develop highly-integrated photonic chips for
further advance of nano-photonics.
