The papers included in this dataset primarily investigate broadband optical vector analysis based on microwave photonic downconversion. The core of this technique relies on leveraging the second-order nonlinear characteristics of electro-optic modulation, where two pairs of swept dual-tone signals with distinct frequency intervals serve as the probe light. Subsequently, this technique was applied to measure the amplitude and group delay of one device under test (DUT). During the experiments, a laser, spectrometer, and spectrum analyzer were utilized for data measurement and acquisition. Matlab software was used to plot the acquired data and conduct simulations to generate the relevant experimental result figures presented in the papers. The total data volume is 15.6 MB.
