Abstract:
An optical receiving device includes multiple input ports to which light is input; multiple amplifiers that are arrayed and provided corresponding to the input ports, respectively, each of the amplifiers amplifying and outputting light input from a corresponding input port among of the input ports; a photo diode that converts light into an electrical signal; and a lens that inputs to the photo diode light output from the amplifiers.
