Abstract:
In one aspect, a photonic device includes a first region having a first doping type, where the first region is divided into an upper portion made of silicon-germanium and a lower portion made of silicon. The device further includes a second region having a second doping type. The first region and the second region contact to form a vertical PN junction.
