Abstract
- The regulation of PT symmetry in the PT (Parity-Time) symmetric optical waveguide system is mainly realized by the periodic change of complex refractive index materials. In this paper, we give a configuration of manipulating the PT symmetry for the neutral waveguide with additional periodic modulation in the coupled dual-channel waveguide system. After the system is converted into an equivalent unmodulated system with renormalization parameters by high-frequency approximation, it is found that the PT symmetry of the system can be regulated by introducing an additional single-frequency periodic modulation optical waveguide, and the energy spectrum characteristics of the system with periodic modulation of non-Hermitian three-channel waveguide are discussed, Finally, the dynamic evolution of light in non-Hermitian three-channel optical waveguide is given by analytical and numerical methods.
