Abstract: An optical coupling apparatus and method are described. An embodiment of an optical coupling apparatus may include a first optical chip, a second optical chip, and an optical writing waveguide block. In the apparatus, the first optical chip is coupled to the optical writing waveguide block in a first coupling manner, and the second optical chip is coupled to the optical writing waveguide block in a second coupling manner. Furthermore, in the apparatus, the first optical chip is optically interconnected to the second optical chip by using the optical writing waveguide block. Compatibility between a plurality of coupling manners is therefore enabled by using the technical solutions described herein.
