Lithium niobate intensity modulators alter the refractive index of lithium niobate waveguides via externally applied radio frequency (RF) signals, thereby modulating the intensity of input continuous-wave (CW) lasers and encoding RF information onto optical carriers. They play a core role in radio-over-fiber (RoF) applications such as wireless communication over optical links, and their performance directly determines the signal quality, transmission distance, and system efficiency of the link.

A low half-wave voltage of lithium niobate intensity modulators can enhance signal conversion efficiency, high linearity can expand the dynamic range of the link, and high bandwidth can accommodate more application scenarios such as large-scale millimeter-wave and satellite communications.

In the high-speed broadband parallel analog signal optoelectronic transceiver module studied in this project, the independently developed lithium niobate intensity modulator chip is the core device, whose performance determines the achievement of key indicators including the project's operating bandwidth, noise figure, half-wave voltage, and spurious-free dynamic range.

This dataset is mainly targeted at research on electrode simulation and indicators such as operating bandwidth and half-wave voltage of lithium niobate intensity modulator chips. The data collection period spans from 2021 to 2024, and it mainly records the simulation parameters of buffer layer thickness, electrode thickness, electrode spacing, and electrode width of lithium niobate intensity modulator chips, as well as the test data of the modulator chips' S-parameters and half-wave voltage, with a total data volume of 8.29 MB.

The simulation data was collected using the professional 3D electromagnetic simulation software HFSS, while the measurement data was collected using professional instruments such as network analyzers, current source meters, oscilloscopes, and signal generators.

The quality control measures of this dataset include multiple experimental repetitions, standard sample comparison, and signal deviation analysis, etc., to ensure the accuracy and stability of the data.

This dataset can be used as a design reference for similar intensity modulator chips, and provides basic data for the development of related optoelectronic devices and modules.
