Imaging lattice switching with Talbot effect in reconfigurable non-Hermitian photonic graphene
文献摘要：
By taking advantage of the optical induction method,a non-Hermitian photonic graphene lattice is efficiently established inside an atomic vapor cell under the condition of electromagnetically induced transparency.This non-Hermitian structure is accomplished by simultaneously modulating both the real and imaginary components of the refractive index into honeycomb profiles.The transmitted probe field can either exhibit a hexagonal or honeycomb intensity profile when the degree of non-Hermiticity is effectively controlled by the ratio between imaginary and real indices.The experimental realization of such an instantaneously tunable complex honeycomb potential sets a new platform for future experimental exploration of non-Hermitian topological photonics.Also,we demonstrate the Talbot effect of the transmitted probe patterns.Such a self-imaging effect based on a non-Hermitian structure provides a promising route to potentially improve the related applications,such as an all-optical-controllable Talbot-Lau interferometer.
