A device (1) comprises optical communication means, which includes a substrate (2) on which are provided a light-emitting element (3), a driver circuit for driving the light-emitting element (3), a photodetector element (5) (photosensor element), a light guide (4) (waveguide) for guiding light from the light-emitting element (3) to the photodetector element (5), an amplifier circuit (6), a connection (7) (electric wiring) and a circuit (8). The light (optical signal) from the light-emitting element (3) is introduced through the light guide (4) to the photodetector element (5), where the light is subjected to photoelectric conversion. The electric signal from the photodetector element (5) is amplified by the amplifier circuit (8) and input to the circuit (8) through the connection (7), thus operating the circuit (8). |
