We apply gain/loss to honeycomb photonic lattices and demonstrate that optical tachyons, a photonic version of particles that travel faster than the speed of light, can be generated by PT-symmetry breaking in this structure. We further show that the PT-symmetry can be restored via strain.

We apply gain/loss to honeycomb photonic lattices and show that the dispersion relation is identical to tachyons – particles with imaginary mass that travel faster than the speed of light. This is accompanied by PT-symmetry breaking in this structure. We further show that the PT-symmetry can be restored by deforming the lattice.
