Abstract
An example optical polarization controller can include a substantially planar substrate and a waveguide unit cell formed on the substantially planar substrate. The waveguide unit cell can include a first out-of-plane waveguide portion and a second out-of-plane waveguide portion coupled to the first out-of-plane waveguide portion. Each of the first and second out-of-plane waveguide portions can respectively include a core material layer arranged between a first optical cladding layer having a first stress-response property and a second optical cladding layer having a second stress-response property. The first and second stress-response properties can be different such that each of the first and second out-of-plane waveguide portions is deflected by a deflection angle.
