Vortex creation without stirring in coupled ring resonators with gain and loss
Aleksandr Ramaniuk, Nguyen Viet Hung, Michael Giersig +3
We present study of the dynamics of two ring waveguide structure with space dependent coupling, linear gain and nonlinear absorption - the system that can be implemented in polarit…

Symmetry breakings in dual-core systems with double-spot localization of nonlinearity
Krzysztof B. Zegadlo, Nguyen Viet Hung, Aleksandr Ramaniuk +2
We introduce a dual-core system with double symmetry, one between the cores, and one along each core, imposed by the spatial modulation of local nonlinearity in the form of two tig…
