Abstract
An optical coupling connector, an optical coupling system, and a waveguide coupling method are provided. The optical coupling connector is configured to connect an optical fiber array and an optoelectronics chip, and includes an upper-layer connector and a lower-layer connector. The upper-layer connector includes N upper-layer waveguides, where N is a positive integer greater than or equal to 2. The lower-layer connector includes N lower-layer waveguides. The N lower-layer waveguides and the N upper-layer waveguides are coupled in a one-to-one correspondence. Each lower-layer waveguide includes a coupling waveguide portion, a pitch matching waveguide portion, and a signal light amplification waveguide portion.
