Abstract
An optical coupling module includes a substrate, a circuit board defining two through holes, an optical waveguide positioned between the substrate and the circuit board, and an optical assembly. The optical waveguide includes a core and a clad, each core comprises two coupling surfaces corresponding to the two through holes. At least one coupling surfaces is in an arcuate shape. The clad covers the core, except for the two coupling surfaces exposing out of the clad. The optical assembly formed on the circuit board comprises an optical emitting element and an optical receiving element. The optical emitting element and the optical receiving element are positioned above the two through holes, respectively. Light emitted from the optical emitting element enters the optical waveguide via one of the coupling surface, and leaves from another coupling surface to reach the optical receiving element. The coupling surface is capability of focusing light.
