Compact Lithium-Niobate-on-Insulator Polarization Rotator Based on Asymmetric Hybrid Plasmonics Waveguide

We proposed a compact and efficient polarization rotator (PR) based on an asymmetric hybrid plasmonics waveguide (HPW) on the lithium-niobate-on-insulator (LNOI) platform. We focus on the design of rotation angle and balance between the two hybrid modes. The presented device exhibits a polarization...

Description
Summary:We proposed a compact and efficient polarization rotator (PR) based on an asymmetric hybrid plasmonics waveguide (HPW) on the lithium-niobate-on-insulator (LNOI) platform. We focus on the design of rotation angle and balance between the two hybrid modes. The presented device exhibits a polarization extinction ratio as high as 59.58&#x00A0;dB and an insertion loss of 1.44&#x00A0;dB with the rotation length of only 13.7&#x00A0;<inline-formula><tex-math notation="LaTeX">$\mu$</tex-math></inline-formula>m. The fabrication tolerances and a suitable process are also discussed to meet the state-of-art technology.
