Demonstration of a two-dimensional $${\cal P}{\cal T}$$ PT -symmetric crystal
To date, experimental demonstrations of PT-symmetric systems have been restricted to one dimension. Here, the authors experimentally realize and characterize a two-dimensional PT-symmetric system using photonic lattice waveguides with judiciously designed refractive index landscape and an alternatin...
