Design and analysis of all-optical nibble multiplexer with tri-stated outputs using micro-ring resonator structure

The manuscript describes an efficient theoretical mechanism to implement the all-optical nibble multiplexer with tri-stated output using the micro-ring resonator (MRR) structure. The proposed article introduces the concept of ultrafast all-optical switching on a nonlinear material (GaAs-AlGaAs)-based MRR structure using the optical pumping method. Further, the switching activity of MRR is used to design the proposed all-optical nibble multiplexer with tri-stated outputs. The design technique involves the additional advantage of all-optical units. The complete layout of the proposed design is mathematically explained, and the desired results are proved using MATLAB simulation software. The article also discusses how to efficiently pick device settings by analyzing performance metrics such as coupling coefficients and radius of MRR structure. The performance affecting parameters of MRR are also analyzed in a detailed manner, which shows the suitability of the proposed unit in the all-optical domain. The design achieves a higher figure of merits, which increases the acceptability of such a device for the future ultrafast all-optical communication system.
