Abstract: (670 Views)
In this paper, the propagation pattern of the light in a PT-symmetry ladder optical waveguide array with a Fibonacci refractive index profile is investigated. After that, using a criterion based on light intensity, the PT-symmetry breaking point is calculated at different propagation constant values. Numerical results show that the PT-symmetry breaking point has a maximum at a certain value of the propagation constant
