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 first portion having a first width and a second portion having a width different from the first width and located on the first portion. The first portion is located between a first doped region and a second doped region.
