Abstract
Embodiments of the present invention provide an optical structure, an optical coupling method, and a photonic integrated circuit chip. The optical structure includes: two optical coupling structures with different structures, that is, a first optical coupling structure and a second optical coupling structure. The first optical coupling structure includes a first optical transmission structure, and a first coupling port and a second coupling port both connected to the first optical transmission structure. The second optical coupling structure includes a second optical transmission structure, and a third coupling port and a photoelectric conversion structure both connected to the second optical transmission structure. When optical signals are provided in different methods or optical coupling is performed in different scenarios, optical signal coupling can be realized by using optical coupling structures of different structures in the abovementioned optical structure.
