(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)We study theoretical models of three coupled wave guides with a PT-symmetric distribution of gain and loss. A realistic matrix model is developed in terms of a three-mode expansion. By comparing with a previously postulated ...
