Nonlinear breaking of PT symmetry in coupled waveguides with balanced gain and loss
Xu, Zhiyong; Sukhorukov, Andrey; Kivshar, Yuri
Description
We predict that in coupled waveguides with balanced gain and loss, featuring stationary PT-symmetric modes in the linear regime, nonlinearity results in symmetry breaking above a critical power threshold, leading to sharp beam switching.
