Submicron 1xN Ultra Wideband MIM Plasmonic Power Splitters

A novel design of a submicron power splitter is presented using plasmonics with the metal insulator metal (MIM) configuration. A simple analytical model is utilized to obtain good initial design. The final optimized design is obtained using finite-difference time domain based optimization. The proposed approach provides a simple and efficient methodology for designing 1xN power splitters using MIM configuration. The proposed power splitters are ultra wide band(~ 2 μm) with negligible imbalance. The approach is utilized to design up to 1 × 4, 1 × 8, and 1 × 16 integrated power splitters with submicron footprint, where all the optimized designs are validated.
