Vertical cavity surface emitting lasers (VCSELs) have the advantages of low loss, good beam quality, high fiber coupling efficiency, high modulation rate and easy integration with other optoelectronic devices. They have developed rapidly in the fields of optical interconnection, optical storage, high-speed transmission and date communication. With the advent of the big data era, higher requirements have been put forward for the establishment of high-speed optical communication networks with high bandwidth and low loss. Therefore, in recent years, VCSELs have been extensively studied in high-speed data communications to increase the modulation rate and reduce energy loss. Firstly, the basic structure of the 850/980 nm VCSEL devices in the near-infrared band used in short-distance data communications is introduced. And then a reasonable theoretical design is made from the factors affecting high-speed performance, the research progress of the high-speed performance of 850/980 nm VCSEL is introduced. Finally, the future development trend of VCSEL in the field of data communication is prospected.
