An injection modulator for modulation of optical radiation, having an optical waveguide and a diode structure, having at least two p-doped semiconductor portions, at least two n-doped semiconductor portions and at least one lightly or undoped intermediate portion between the p-doped and n-doped portions. The p-doped portions when viewed in the longitudinal direction of the waveguide are offset with respect to the n-doped portions and the diode structure is arranged in a resonance-free portion of the waveguide. The p-doped portions lie on one side of the waveguide, the n-doped portions lie on the other side of the waveguide and the intermediate portion lies in the center, each portion extends transversely with respect to the waveguide longitudinal direction in the direction of the waveguide center of the waveguide and no p-doped portion when viewed in the longitudinal direction of the waveguide overlaps any n-doped portion.
