Three-dimensional (3D) optical waveguides were fabricated in a photopolymer izing resin mixture solution by using a multimode optical fiber, without an y moving parts. The core portion has formed by the selective photopolymeriz ation of a higher refractive index monomer by Ar+ laser irradiation through the optical fiber. A continuous, straight waveguide was grown by the self- trapping of a guided laser beam. We demonstrated automatic 3D optical circu it formation that enables regrowth after passing through thick transparent glass plates. This growth mechanism also enables automation of the optical interconnection and packaging process, and could potentially contribute to future expansion of optical fiber communications networks.
