Abstract
Provided are: a photon detection light-receiving device with which it is possible to avoid malfunctions caused by the application of high voltages, and to shorten the delays in communication time in mesh-type network communication; and a communication apparatus equipped with the photon detection light-receiving device. The photon detection light-receiving device has a photon detection APD, a quenching resistor and a capacitor, with one end of the quenching resistor and one end of the capacitor being connected to one terminal of the photon detection APD. The optical wireless communication apparatus comprises: a housing; a photon detection light-receiving device that generates an electrical signal from received light; a receiving unit that generates a reception data signal using an electrical signal from the photon detection light-receiving device; a transmission unit that generates an electrical signal using a transmission data signal; a light emitting device into which the electrical signal from the transmission unit is input and generates transmission light; and an optical wireless communication controller that generates transmission data or reception data corresponding to the pro…
