Abstract:
A photoelectric converter connectable to an external antenna for wireless communication, comprising:a laser having a first resonation mirror and a second resonation mirror that define an active layer therebetween, and a pair of electrodes that supply energy to generate a laser beam; a third mirror positioned to receive the laser beam emitted from the laser; a channel provided between the third mirror and the laser that transmits the laser beam from the laser to the third mirror; and plural electrodes that supply electrical energy to the channel, one of the electrodes being connectable to the external antenna so that the photoelectric converter can serve as one of an uplink and a downlink, wherein when the photoelectric converter is operating as an uplink, an incoming electrical signal from the external antenna is receivable by a gate electrode of the plural electrodes, which modulates the output of the laser beam to convert the electrical signal into a corresponding optical signal, and wherein when the photoelectric converter is operating as a downlink, an optical signal from the laser beam operates on the channel and current between the plural electrodes may be provided to the external antenna to convert the optical signal into an electrical signal for transmission.
