1. A method comprising:
receiving an optical signal having a first polarization state at a first section of a waveguide, the first section of the waveguide being disposed on a plane of a substrate;
using a micro-electromechanical system (MEMS) device, angling a second section of the waveguide out of the plane of the substrate, the second section of the waveguide being U-shaped; and
outputting the optical signal with a second polarization state, different from the first polarization state, on a third section of the waveguide, the third section of the waveguide also being disposed on the plane of the substrate.
