Abstract
A system includes a pixel having a diffusion layer within a cap layer. The diffusion layer defines a front side and an illumination side opposite the front side with an absorption layer operatively connected to the illumination side as well as the diffusion and cap layers. A set of alternating oxide and nitride layers are deposited on the front side of the cap and diffusion layers.
