A near-infrared optical power meter circuit with large dynamic range is designed based on indium gallium arsenide (InGaAs) photodiode. It can measure near-infrared optical power in the range of -95--10 dBm without using an external optical attenuator. The optical power meter circuit adopts technologies such as automatic bias voltage control, multi-level amplification range, differential sampling circuit, etc ., and suppresses stray light noise and dark noise through electromagnetic shielding design, thereby improving the measurement dynamic range. The test results show that the dynamic range of this near-infrared optical power meter circuit reaches 105 dB, and the linearity in the range of -60--10 dBm is less than ±002 dB.
