A semiconductor photodiode, including a light-absorbing layer; an optical waveguide via which light can evanescently be coupled into the light-absorbing layer, and a doped contact layer arranged between the light-absorbing layer and the optical waveguide. The optical waveguide at least sectionally has a doping which produces a diffusion barrier counteracting a diffusion of dopant of the contact layer into the optical waveguide.
