InGaAs trap detector used as a near-infrared transfer standard for detector calibrations

摘要

This paper presents results of investigations of the radiant power spectral responsivity within the near-infrared spectral range. Large-area windowless InGaAs photodiodes of 10mmx10mm are studied in the spectrum ranged from 900 nm to 1600 nm.The InGaAs trap detector used as a transfer standard for power measurements has been characterized and calibrated, obtaining an uncertainty of less than 0.1% at several wavelengths.
