Abstract: (778 Views)
In this paper, the parity-time symmetry (PT-symmetry) breaking point of two curved optical waveguides in the presence of nonlinear Kerr effect is investigated. For this purpose, light propagation for different cases of presence and absence of loss/gain, as well as the presence and absence of nonlinear effect has been investigated. The numerical results show that the nonlinear effect causes the self-focusing effect, and therefore by reducing the effective coupling coefficient between the waveguides, reduces the PT-symmetry breaking point.
