1. A device comprising:
a substrate; and
a photodetector coupled to the substrate,
wherein the photodetector is arranged to detect light emitted from a light source, and
wherein a structure of a surface of the substrate mitigates dark current arising from minority carriers photoexcited in the substrate based on the light emitted from the light source.
