摘要：A driving device including a light emitter, a biasing circuit, a light receiver, anautomatic control system, and an alternating current (AC) path is disclosed. The lightemitter generates an optical signal. The biasing circuit generates a driving signal toactivate the light emitter such that the light emitter operates in a working range. The
light receiver detects the output power of the optical signal for generating a
corresponding electrical signal. The automatic control system adjusts the driving signalaccording to the corresponding electrical signal such that the output power of theoptical signal approaches a preset value. The AC path is coupled between the lightemitter and an external signal source for receiving at least one AC modulated signal suchthat the light emitter generates at least one modulated optical signal.
