Abstract
An optical switch having regions to which conductors are coupled outside an optical path of the optical switch. In one embodiment, the disclosed optical switch includes a plurality of first polarity regions arranged along an optical waveguide disposed in a semiconductor substrate layer. A first polarity region signal line conductor is in contact with each one of the plurality of first polarity regions outside an optical path of the optical waveguide. A plurality of second polarity regions are arranged along the optical waveguide disposed in the semiconductor substrate layer. A second polarity region signal line conductor is in contact with each one of the plurality of second polarity regions outside the optical path of the optical waveguide.
