Abstract
A photodetector includes a substrate, an optical absorber, a first doped region, a second doped region, and a third doped region. The optical absorber is disposed in the substrate and includes a first region and a second region. The first doped region is disposed in the substrate such that the first doped region contacts the second region of the optical absorber. The second doped region is disposed in the substrate such that the second doped region contacts the second region of the optical absorber. The second region of the optical absorber is positioned between the first doped region and the second doped region. The third doped region is disposed in the substrate and has an opposite doping relative to the first doped region and the second doped region. The first region of the optical absorber is positioned between the third doped region and the second region of the optical absorber.
