Description

technical field [0001] The invention belongs to the technical field of all-optical communication systems, and relates to an optical bistable device applied to all-optical switches and optical memories. Background technique [0002] With the development of all-optical network and information detection technology, there is an urgent need to develop all-optical switches and optical memories. The material-based optical bistability effect can realize all-optical switches and optical memories. [0003] In the past, surface plasmon polaritons (SPPs) or Fabry-Perot cavity structures were generally used to enhance the localization of the electric field, and then materials with large nonlinear coefficients were used to achieve low-threshold optical dual steady state. [0004] SPPs require TM waves to be generated in metals or graphene, and SPPs only go along the surface of the material. Moreover, SPPs can only be excited in metamaterials and Kretschmann structures. [0005] As an ...
