Silicon germanium imager with photodiode in trench
An optical apparatus that includes: a semiconductor substrate formed from a first material, the semiconductor substrate including a first n-doped region; and a photodiode supported by the semiconductor substrate, the photodiode including an absorption region configured to absorb photons and to generate photo-carriers from the absorbed photons, the absorption region being formed from a second material different than the first material and including: a first p-doped region; and a second n-doped region coupled to the first n-doped region, wherein a second doping concentration of the second n-doped region is less than or substantially equal to a first doping concentration of the first n-doped region.
