Abstract: Abstract The existence and stability of nonlinear stationary states in nonlinear saturable coupler with balanced gain–loss (the parity-time symmetric distribution) are studied. Propagation and switching of beams at the different initial excitations are investigated. read more here.

Abstract: We study the three-wave interaction that couples an electromagnetic pump wave to two frequency down-converted daughter waves in a quadratic optical crystal and PT-symmetric potentials. PT symmetric potentials are shown to modulate stably nonlinear modes… read more here.
