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://macorners.shop/product-category/engraved-whiskey-glass/
