A waveguide having a bi-directional optical transmission structure comprises: a main waveguide which is formed in a preset direction; a branch waveguide which is connected to at least one of both ends of the main waveguide; and a reflector which is placed at an intersection where the branch waveguide and the at least one of both ends of the main waveguide are connected, and which has a different refraction index from the refraction index of the main waveguide and the refraction index of the branch waveguide, wherein the reflector refracts or reflects an incoming transmission light signal and an incoming reception light signal in different forms, and thereby directs the incoming transmission light signal to the main waveguide, and separates the incoming reception light signal to the branch waveguide.

A waveguide of a 3D connecting structure comprises: a main waveguide formed in a preset direction; and at least one branch waveguide connected to the main waveguide at a preset angle. At least one branch waveguide branches an optical signal progressing in the main waveguide at a preset rate. COPYRIGHT KIPO 2016 ...
