Localization and Steering of Light in One-Dimensional Parity-Time Symmetric Photonic Lattices

摘要

We theoretically study the propagation dynamics of input light in one-dimensional mixed linear-nonlinear photonic lattices with a complex parity-time symmetric potential.Numerical computation shows simultaneous localization and steering of the optical beam due to the asymmetric scatter and interplay between Kerr-type nonlinearity and PT symmetry.This may provide a feasible measure for manipulation light in optical communications,integrated optics and so on.
