Abstract

We have explored the polarization behavior of MoS₂ at three different wavelengths using a polymer-based waveguide. The MoS₂-coated waveguide has been fabricated based on the drop casting method. The maximum polarization extinction ratio of 12.6 dB that is achieved at 980 nm is considered to be the highest, to the best of our knowledge, for the MoS₂-based waveguide polarizer. It exhibits transverse electric (TE) pass characteristics in the visible wavelength region. The mode field confinement has been computed based on the finite-element method (FEM). Both numerical and experimental results are in very good agreement. These results demonstrate that the few-layer MoS₂ can be considered as a complementary material for graphene-based polarizers.
