Abstract
A waveguide photoelectric detector, comprising: a substrate comprising a silicon layer, the silicon layer having a silicon waveguide formed thereon; an active layer dispose on the silicon waveguide, the active layer having a first doped region formed thereon; a horizontal PIN junction formed at an area of the silicon layer below the active layer, the horizontal PIN junction comprising a second doped region, an intrinsic region, and a third doped region. A doping type of the second doped region is the same as that of the first doped region. One end of the second doped region near the intrinsic region is connected to the first doped region. The third doped region and the first doped region form a vertical PIN junction.
