ABSTRACT:
Optical switches are described herein. In one embodiment, an exemplary optical switch includes, but is not limited to, a first waveguide, a second waveguide across with the first waveguide in an angle to form an intersection, and a pair of electrodes placed within a proximity of the intersection to switch a light traveling from the first waveguide to the second waveguide, where at least one of the electrodes includes a non-uniform edge to deflect a light remained after switching from the first waveguide to the second waveguide to a direction other than a direction associated with the first waveguide. Other methods and apparatuses are also described.
