Abstract

Over the past two decades, topological insulators (TIs) [1] and Parity-Time (PT)-symmetry [2] have both have both driven a number of new research avenues in photonics. While the synthesis of these two concepts has recently been considered theoretically [3-5], the experimental realization of a genuine two-dimensional PT-symmetric TI remains elusive to this day.
