Abstract
A vertical photodiode includes an active area. The contacting pads for the diode terminals are laterally shifted away from the active area so as to not be located above or below the active area. The active area is formed in a layer of semiconductor material by a lower portion of a germanium area that is intrinsic and an upper portion of the germanium area that is doped with a first conductivity type. The vertical photodiode is optically coupled to a waveguide formed in the layer of semiconductor material.
