Light-receiving device, light receiver using same, and method of fabricating light-receiving device

A light receiver, comprising:

• a light-receiving device, including:
• a flip-chip semiconductor substrate,
• a light detection element configured to be formed over the flip-chip semiconductor substrate and to have a laminate structure including a first-conductive-type first semiconductor layer, a light-absorption layer formed over the first semiconductor layer, and a-second-conductive-type second semiconductor layer formed over the light-absorption layer,
• an inductor configured to be connected over the light detection element on the flip-chip semiconductor substrate,
• an output electrode for bump connection configured to output a current generated by the light detection element through the inductor,
• a bias electrode for bump connection configured to apply a bias voltage to the light detection element through a bias electrode, and
• a line configured to cause a metal line of the inductor and the light detection element to be connected to the output electrode or the bias electrode;
• an optical signal demodulator configured to demodulate a demodulation process on a light signal supplied from an optical transmission path;
• a photoelectric converter configured to convert a light signal component obtained through the light signal process into an electric signal using the light-receiving device;
• a digital converter configured to convert the electric signal obtained through the photoelectric conversion into a digital signal;
• and
• a digital signal processor configured to process the digital signal.
