An edge emitting optoelectronic source is integrally formed on a surface of a semiconductor substrate. An optical waveguide is integrally formed on the same surface of the substrate adjacent to the source. The waveguide is aligned with the source for optical coupling of the source to the waveguide. The waveguide comprises an optical diverter for diverting at least a portion of any light propagating along the waveguide toward the source through a surface of the waveguide. An optoelectronic detector is secured to that surface of the waveguide through which light is diverted for receiving light diverted through that surface. The resulting optoelectronic apparatus is suitable for launching and detecting optical signals in large volume bidirectional optical fiber transmission systems.
