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 the intersection includes a geometry that supports single and multimode propagation. The intersection includes a geometry having a ridge width ranging approximately from 2.6 mum to 19.2 mum and a ridge height ranging approximately from 4 mum to 16 mum. Other methods and apparatuses are also described.
