Simulation of microring resonator filters based ion-exchange buried waveguide using nano layer of graphene

Abstract

Silver ion-exchange in the glass reveals to be a highly promising method if the low loss waveguide fabrication in the context of optical interconnects demanded. Silver ion-exchange is a well-known method that Ag+-ions from the AgNO3 melt exchanged with mixed Na+-ions of the glass, even not high-temperature low solubility of the elementary silver can cause the ion-exchange in glass have silver as submicroscopic crystals. The distribution of electric fields in the form of contour plots from different perspectives namely, topside, the front side (input port) and backside (output port) and the evaluation on the basis of confined power density in the Ag+ buried waveguide are presented. The microring resonators (MRRs) is proposed as an application for the ion-exchange buried waveguide. In this research, we use the time-domain traveling wave method to model and simulate the MRR utilizing the ion-exchange buried waveguides. Two MRRs are embedded to an MRR add/drop to perform tunable dual-wavelengths. Therefore, this system can be used to generate multiple dual-wavelengths with spacing in the range of GHz in the frequency domain. The generated dual-wavelengths have ranged between 43 and 314 GHz. These signals have many applications in optical sensing, radio frequency radiation, optical communication, optical switching, millimeter wave generators and biological research.
