Abstract
A comparison measurement of absolute power responsivity of silicon photodetector between He-Ne laser and supercontinuum white light source has been realized recently. The power responsivity of silicon trap detector at 632.8nm has been transferred from NIM’s primary optical power standard-the absolute cryogenic radiometer. A 0.07% difference was present for the two different light sources at the same wavelength. Also, a series of experiments related to the comparison have been done including measurement of source power stability, detector polarization dependence, uniformity, and angular dependence. At last, the measurement uncertainty of the comparison is analyzed.
