Abstract: An optoelectronic device includes a silicon substrate, with a silicon waveguide layer disposed over the silicon substrate and including an optical waveguide. One or more through-silicon vias (TSVs) extend through the silicon substrate and contact the silicon waveguide layer. A III-V base layer is disposed over the silicon waveguide layer, and an optical amplifier is disposed on the III-V base layer and optically coupled to the optical waveguide.

Abstract: An optoelectronic device includes a substrate, having a recess formed therein. An optical isolator is mounted in the recess. A laser includes a stack of epitaxial layers on the substrate and emits a beam of radiation toward the recess along a direction parallel to a surface of the substrate. A waveguide directs the beam emitted by the laser into the optical isolator.

Abstract: An optoelectronic device includes a substrate and at least three emitters, which are disposed on the substrate and are configured to emit respective beams of light. A plurality of waveguides are disposed on the substrate and have respective input ends coupled to receive the beams of light from respective ones of the emitters, and curve adiabatically from the input ends to respective output ends of the waveguides, which are arranged on the substrate in an array having a predefined pitch. Control circuitry is configured to apply a temporal modulation independently to each of the beams of light.
