Abstract

A novel approach, using a PNA(network analyzer) instead of Spectrum Analyzer in optical heterodyne measurement system, to characterize the frequency response performance of photodetectors is proposed. This scheme synthesize the advantages of both the optical heterodyne technique and accurate calibration technique of PNA. In this paper, two tunable narrow linewidth lasers are used to reduce the errors caused by the variations in the linewidth of the beat signal, and the optical power is accurately monitored and controlled to minimize the noise due to laser output power fluctuates. We analyze the influence of variations linewidth, and associative simulation on this influence is been done. And an error eliminate model is presented to remove the influence of variations linewidth. SOLT calibration technique is used to accurately calibrate the power receiver of PNA. In addition, when configured with an 80 GHz frequency mixer in this measurement system, we can achieve the frequency response measurement of a 80 GHz photodetector since we are using a 40 GHz PNA.
