Abstract
A photonic device includes a substrate, a P-type doped component disposed over the substrate, an N-type doped component disposed over the substrate, an optical absorption layer disposed over the substrate, and a charging layer disposed over the substrate. The optical absorption layer is disposed between the P-type doped component and the N-type doped component. The optical absorption layer and the substrate have different material compositions. A charging layer is disposed between the P-type doped component and the N-type doped component. The charging layer has a first side surface that is substantially linear. The first side surface is in direct contact with the optical absorption layer.
