Abstract
AbstractIn this paper, the performance analysis on hybrid plasmonic waveguide (HPW)-based symmetrical directional coupler (DC) is proposed, which contains two parallel arms. In this analysis, one HPW arm performs as an input port and bar (parallel) output port; another HPW arm doings as a cross output port. The principle of DC is satisfied by the coupling of transverse magnetic field (TM) from the bar port to cross port. In the proposed DC, the mode characteristic parameters such as normalized mode area and propagation length are calculated by finite element method (FEM), and performance of the device is analyzed by certain parameters such as propagation loss, cross-talk, insertion loss, and coupling ratio. Hence, the proposed DC is designed with low cross-talk, low insertion loss, low propagation loss, and high propagation length, which could be appropriate for ultra-dense photonic integrated circuits (PICs).KeywordsOptical waveguidesDirectional couplerFinite element method
