Abstract
With high quantum efficiency, low capacitance, low dark current and wide bandwidth, InGaAs detectors has lots of applications in optical radiation measurement, optical communication and remote sensing. This paper using a spectral comparison facility based on supercontinuum white light source and double monochromator, in which a reference InGaAs trap detector is used for the relative spectral responsivity calibration of a planar InGaAs detector. Calibration of the same detectors using tungsten lamp as light source has also been done and shows a good consistency, which proves the feasibility of relative spectral responsivity calibration using supercontinuum white light sources.
