Abstract
A photodiode includes a cap layer defining an inboard side and an outboard side. A plurality of pixels are formed in the cap layer extending from the inboard side to the outboard side. At least a portion of the cap layer is defined in between the pixels. A metal barrier is in between the pixels and is operatively connected to the inboard side of the cap layer in between the pixels to reflect light rays into the cap layer reducing the leakage of photons between the pixels.
