Hermiticity-tunable beam reshaping: localization, recurrence and group velocity oscillation

Hermiticity-tunable beam reshaping: localization, recurrence and group velocity oscillation

We propose a novel method to reshape the light beam in a Hermiticity-tunable photonic lattice with PT symmetric perturbations. By adjusting the PT perturbations, the Hermiticity of the system varies alternatively, further resulting in the periodic oscillations of the group velocity ( v _g ) as well...
