In this paper, a Si3N4-CaF2 hybrid plasmonic waveguide (HPW) with an asymmetric metal cladding is designed for the mid-infrared polarization rotator (PR). The mode characteristics and polarization rotation performances of the Si3N4-CaF2 HPW-based PR are simulated by using the finite element method. Operating at the wavelength of 3.5 µm, the polarization conversion efficiency between two polarization modes (PM 1 and PM 2) is larger than 99% at a Si3N4-CaF2 HPW length of 104 µm. The Si3N4-CaF2 HPW-based PR maintains good polar
