Abstract

An optical switch device includes a first semiconductor structure configured to operate as a first waveguide and a second semiconductor structure configured to operate as a second waveguide. The second semiconductor structure is located above or below the first semiconductor structure and separated from the first semiconductor structure. The second semiconductor structure includes a portion of a first doped region doped with dopants of a first type and a portion of a second doped region doped with dopants of a second type that is different from the dopants of the first type.
