Abstract

We propose a novel ultracompact (5 μm) hybrid plasmonic polarization rotator operating at telecommunication wavelength for integrated silicon photonic circuits. The polarization mode of a silicon waveguide is rotated with >14dB polarization extinction ratio and low total insertion losses of 2.1 dB.

(a) Top view of the proposed polarization rotator, where the black dashed lines separate the three sections: input taper, rotation section, and output taper. The orange dotted lines indicate the cross sections for which the mode profile is plotted in Fig. 2(b). (b) 3D schematics (not to scale) of the proposed rotator. Green corresponds to silicon, grey is silver. The silica is not shown for clarity.
