Polarization rotation using Molybdenum trioxide in 3 µm SOI platform

Abstract

We propose a novel polarization rotator concept using two-dimensional (2D) anisotropic materials, such as molybdenum trioxide, on top of 3µm silicon waveguides. The in-plane anisotropic behaviour of 500 nm thick MoO3 flake is analysed and confirmed with Raman spectroscopy.
