Abstract
A semiconductor device is provided. The semiconductor device includes a waveguide over a first dielectric layer. A first portion of the waveguide has a first width and a second portion of the waveguide has a second width larger than the first width. The semiconductor device includes a first doped semiconductor structure and a second doped semiconductor structure. The second portion of the waveguide is between the first doped semiconductor structure and the second doped semiconductor structure.
