Phase transition through the splitting of self-dual spectral singularity in optical potentials

Vladimir V. Konotop, Dmitry A. Zezyulin

We consider optical media which feature antilinear symmetries. We show that: (i) spectral singularities of such media (if any) are always self-dual, i.e., correspond to CPA-lasers;…

$C P T$ -symmetric coupler with intermodal dispersion

Dmitry A. Zezyulin, Yaroslav V. Kartashov, Vladimir V. Konotop

A dual-core waveguide with balanced gain and loss in different arms and with intermodal coupling is considered. The system is not invariant under the conventional $P T$ symmetry but…
