摘要

We report a method to significantly improve the accuracy of an optical vector network analyzer (OVNA) with double-sideband (DSB) modulation. The measurement errors of the DSB-OVNA mainly derive from optical carrier uncertainty and the beating between higher order optical sidebands. We propose a three-step measurement method and an accuracy-enhanced algorithm to eliminate these measurement errors perfectly. A theoretical model is built to analyze the potential measurement errors as well as to find a way to remove them. Excellent accuracy improvement of the OVNA is confirmed by a proof-of-concept experiment. The OVNA shows an ultrahigh resolution of 667 kHz over a wide-hand measurement range of 80 GHz.
