OPTOELECTRONIC DEVICE WITH LATERAL PIN OR PIN JUNCTION
First Claim
1. An optoelectronic device, including a semiconductor body having a surface to receive photons and a plurality of doped regions of opposite doping polarities, the doped regions extending substantially from the surface of the semiconductor body and into the semiconductor body, and being arranged in one or more pairs of opposite doping polarities such that each pair of doped regions forms a corresponding space charge region having a corresponding electric field therein, the space charge region extending substantially from the surface of the semiconductor body and into the semiconductor body such that photons entering the semiconductor body through the surface and travelling along paths within the space charge region generate electron-hole pairs in the space charge region that are separated in opposing directions substantially orthogonal to the photon paths by the electric field and collected by the corresponding pair of doped regions, thereby providing an electrical current to be conducted from the device.
