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 as the group velocity dispersion (GVD). https://www.alarecre.com/Virescent-Harmony-Galaxy-A14-5G-Clear-Case-p106336/
