Abstract
An apparatus includes a substrate and a waveguide coupled to a surface of the substrate. The surface forms a cladding layer of the waveguide. The apparatus includes a photodetector optically coupled to an end of the waveguide. The photodetector is configured to output an electrical signal responsive to receiving a light signal from a core of the waveguide. The apparatus also includes an amplifier device coupled to the substrate. The amplifier device is electrically coupled to the photodetector to amplify the electrical signal to produce an amplified electrical signal.
