Application of "Flow-Graph" Technique in Measurement Calibration of High Frequency Characteristics of Photodetectors
-
Abstract
In order to reduce the inaccuracy of traditional calibration,the "flow-graph" method is proposed.This method takes into account the effects of the inaccuracy of various frequency responses and the mismatch between different ports.Furthermore,a calibration formula is deduced.This method was applied to the further calibration analysis of a typical lightwave component analyzer (LCA)-based photodetector measurement system.The experiment of a novel photodetector demonstrates that in the range of 130MHz to 20GHz,an obvious improvement in the calibration of theS21 parameter has been achieved compared to the traditional algorithm,and the proposed method is proved feasible.-
