▎ 摘　　要

NOVELTY - The coupler (100) has an optical waveguide (120) arranged on a substrate (110). A combiner (130) is fixed on the optical waveguide. A graphene light source radiates first graphene (150) and delivers the first graphene to the optical waveguide through the combiner. The graphene light source is provided with graphene supporting parts (140, 141, 143). Refractive index of the optical waveguide is greater than refractive index of the substrate. A light signal adjustor adjusts intensity of an optical signal generated from the first graphene. The graphene light source radiates second graphene. USE - Optical coupler for use in a communication field. ADVANTAGE - The coupler utilizes the graphene light source, so that compatibility of the electronic component substrate and a light source can be facilitated, and the optical signal generated in the graphene light source can be efficiently induced to the optical waveguide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an optical communication coupler manufacturing method. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of an optical communication coupler.
