Abstract:
Embodiments described herein include an apparatus comprising a semiconductor-based photodiode disposed on a semiconductor layer, and an optical waveguide spaced apart from the semiconductor layer and evanescently coupled with a depletion region of the photodiode. The photodiode may be arranged as a vertical photodiode or a lateral photodiode.
