Abstract:
1. An optoelectronic circuit including: (a) a photoreceptor made in a first semiconductor material that is a silicon substrate, wherein the photoreceptor includes at least one photosensitive area with a pixel array arranged to pick up light; and (b) a laser diode made in a second semiconductor material, different from the first semiconductor material, wherein one part of the laser diode is disposed in a cavity, made through a passivation layer on one part of the photoreceptor, so that the laser diode is mounted in the cavity, and the one part of the laser diode is also electrically connected, in the cavity, directly to the one part of the photoreceptor, and wherein when the laser diode is mounted in the cavity the cavity guides and positions the laser diode in the cavity for the direct electrical connection.
