Abstract-Hybrid plasmonic waveguides with proper design bring about the possibility of both TM and TE mode propagation along with the ability to separate these two modes. This paper aims to design a hybrid plasmonic waveguide working at telecommunication range, which despite its nanoscale dimension is compatible with SOI circuits. Next, polarizer structure is characterized based on geometrical and material variations via finite element method. Finally, the propagation of wave in a compact and optimized structure is investigated by beam propagation method in this paper we show that the best result for the plasmonic polarizer of telecommunication waves achived by selecting Cromium as metal layer of the waveguide and seting a proper thickness for the middle and Silicon layers.
