Abstract
Embodiments provide an optical coupling apparatus, an optical module, and a communications device. In those embodiments, the optical coupling apparatus includes: an optical fiber component, including a plurality of optical fibers and an optical fiber fixing block. The plurality of optical fibers are fixed to the optical fiber fixing block. A first end face is disposed on the optical fiber fixing block. At least some of the optical fibers include plug ends which protrude from the first end face. An optical write waveguide block, including a main body and a plurality of waveguides disposed in the main body. A second end face is disposed on the main body, coupling holes that are in a one-to-one correspondence with the plug ends are disposed on the second end face in a recessed manner, and the coupling holes are formed when ends of the waveguides are recessed from the second end face.
