PURPOSE: To provide an optical power converting circuit obtaining the optimal transmitting efficiency of optical power. CONSTITUTION: The optical power converting circuit is provided with a single photodetector 30 receiving an inputted optical signal and converting the inputted optical signal to a direct current and a DC converting means 40 converting the DC current from the detector 30 to a desired DC output voltage. Consequently, as the signal optical detector 30 is used, inconvenience caused by the uniformity of inputted optical signals to plural photo detectors is eliminated as against a conventional detectors. Thereby, the optical power converting circuit of extremely high efficiency is realized. |
