Abstract
A photodetector includes a photodiode that has a germanium junction formed between an n-doped region and a p-doped region. The germanium junction is formed to have an input interface at a light input end of the germanium junction. The input interface has a substantially flat shape or a convex-faceted shape. The photodetector also includes an input waveguide connected to the input interface of the germanium junction. The input waveguide has a substantially linear shape along a lengthwise centerline of the input waveguide. The input waveguide is oriented so that the lengthwise centerline of the input waveguide is positioned at a non-zero angle relative to input interface of the germanium junction.
