AI Technical Summary
In existing technologies, the difference in optical mode size between single-mode optical fiber and silicon photonic integrated circuit (SiPh) devices leads to high optical power loss. Traditional coupling methods are costly and complex, making it difficult to achieve efficient long-distance data center interconnection.
An optical mode converter was designed, comprising a single waveguide structure, a multilayer waveguide structure, and a transition waveguide structure. The optical mode size is transformed through evanescent field coupling, which reduces optical power loss and simplifies the assembly process.
It achieves efficient coupling between photonic integrated circuits and optical fibers with low loss, reduces assembly complexity and cost, and is suitable for long-distance data center interconnection.
