摘要： Embodiments are provided for a waveguide polarizer comprising a series of bends. The waveguide polarizer is suitable for used in optical waveguide devices or circuits, where a polarized light is required, such as for single polarization output. The polarizer design is independent of the function of the optical devices. In an embodiment, an optical polarizer comprises an optical waveguide configured to propagate light at a designated polarization mode, and comprising a bend in a same plane of the propagated light. The bend has a geometry configured to contain in the optical waveguide the designated polarization mode of the propagated light and radiate outside the optical waveguide a second polarization mode of the propagated light.
