The role of grating and electro-optical to adjustment of optical switches with voltage to graphene layer in increasing bandwidth

The design and simulation of optical switches is of great importance due to the optimal use of the bandwidth and bandwidth available in telecommunication networks. The subject of this article includes the design and simulation of microprocessor resonators and alllight switches with graphene adjustment. In fact, this paper evaluates the optical switches based on the microstructure of the resonator and their electrooptical adjustment by applying voltage to the applied graphene layer. The designed switch has a high scale due to its micrometer size. In fact, in this article, by designing different microcircuit structures of resonators, optical switch with decreasing coefficient and wide bandwidth has been designed.
