Abstract: An optical module includes an emitter and a semiconductor device. The emitter is attached to the semiconductor device and is separated from the semiconductor device by a gap. The semiconductor device includes a waveguide and a diffraction grating located within semiconductor of the semiconductor device. The diffraction grating is a coupling diffraction grating configured to couple light emitted from the emitter into the waveguide. The semiconductor device further includes an additional diffraction grating which is provided on a surface of the semiconductor device which faces the emitter.
