Mode pairs in -symmetric multimode waveguides
Changming Huang, Fangwei Ye, Xianfeng Chen
We study mode properties in multimode optical waveguides with parity-time() symmetry. We find that two guiding modes with successive orders 2\emph{m}-1 and 2\emph{m}…

PT-symmetry in optics beyond the paraxial approximation
Changming Huang, Fangwei Ye, Yaroslav V. Kartashov +2
The concept of the PT-symmetry, originating from the quantum field theory, has been intensively investigated in optics, stimulated by the similarity between the Schrödinger equatio…
