Abstract

A two-tone spectrum analysis method is proposed for self-referenced microwave characterization of high-speed electro-optic phase modulators (PMs) based on the frequency-shifted heterodyning. The method avoids correcting the roll-off responsivity of photodetection and alleviates the bandwidth requirements of the high-speed photodetector and the electrical spectrum analyzer. Moreover, it achieves very high frequency resolution and high stability measurement by the use of the two-tone frequency-shifted heterodyning.
