Abstract
We propose and demonstrate a self-calibrating approach to measure the magnitude response of a broadband electro-optic intensity modulator based on photonic downconversion sampling. A low-repetition-rate mode-locked laser is employed to sample a swept-frequency microwave signal via the modulator under test, where the magnitude response of the modulator is calculated from the relative intensity of the Fourier frequency components in the first Nyquist frequency range and the direct current. In the experiment, magnitude response and half-wave voltage versus frequency of a commercial Mach-Zehnder electro-optic modulator within a frequency range of 0-40 GHz is successfully measured using the proposed method.
