The silicon-based optical interconnect technology is an effective means for breaking the current bottleneck of the electronic interconnects

and the applicable integrated light sources are of great significance to the reduction of size and power consumption of silicon chips.We have seen a series of important breakthroughs in lasers integrated on silicon chips in the past decade or more

and the III-V/Si hybrid integrated laser is one of the most possible solutions among them to be actually applied in the near future.In this paper

we briefly describe its research status

focusing on the research progress and respective problems of the III-V/Si hybrid integrated lasers

including the III-V/Si adhesively bonded laser and the III-V/Si flip-chip laser.Finally

we predict the development orientation of the lasers integrated on silicon.
