  With the intriguing properties of diffraction-free, self-accelerating, and
self-healing, Airy plasmons are promising to be used in the trapping,
transporting, and sorting of micro-objects, imaging, and chip scale signal
processing. However, the high dissipative loss and the lack of dynamical
steerability restrict the implementation of Airy plasmons in these
applications. Here we reveal the hybrid Airy plasmons for the first time by
taking a hybrid graphene-based plasmonic waveguide in the terahertz (THz)
domain as an example. Due to the coupling between an optical mode and a
plasmonic mode, the hybrid Airy plasmons can have large propagation lengths and
effective transverse deflections, where the transverse waveguide confinements
are governed by the hybrid modes with moderate quality factors. Meanwhile, the
propagation trajectories of hybrid Airy plasmons are dynamically steerable by
changing the chemical potential of graphene. These hybrid Airy plasmons may
promote the further discovery of non-diffracting beams with the emerging
developments of optical tweezers and tractor beams.
