Extremely compact slanted waveguide hybrid plasmonic polarization rotator

In this study, we proposed a novel slanted waveguide hybrid plasmonic polarization splitter based on mode evolution at 1.55µm wavelength on silicon-on-insulator technology. The TM polarization is rotated to the TE polarization with a conversion length of 370nm, polarization conversion efficiency of...

Summary:In this study, we proposed a novel slanted waveguide hybrid plasmonic polarization splitter based on mode evolution at 1.55µm wavelength on silicon-on-insulator technology. The TM polarization is rotated to the TE polarization with a conversion length of 370nm, polarization conversion efficiency of 85% and polarization extinction ratio larger than 18dB. •A novel plasmonic (HP) slanted polarization rotator (PR) on silicon-on-insulator was proposed.•The shortest PR which has been reported.•The design of the PR was carried out by using the 3D finite element method.•The polarization conversion length is 370nm with 85% conversion efficiency and 18dB extinction ratio.
