Abstract

Parity-time (PT) symmetric interfaces between amplifying and lossy crystals support dissipationless edge states exhibiting gapless spectra in complex band structure if exceptional points (EPs) of edge states exist, which is verified by rigorous full-wave simulations in PT-symmetric photonic graphene.
