发明名称 METHOD OF MANUFACTURING PREFORM FOR OPTICAL WAVEGUIDE
摘要 <p>The present invention relates to an optical waveguide manufacturing method, which excels in mass productivity of a planar optical waveguide. In an aggregating step, plural members (20), which have a rod (21) or pipe (22) shape respectively, are arranged and bundled so as to constitute a substantially similar figure to at least a part of a desired waveguide pattern on a cross-section perpendicular to the longitudinal direction of the members (20). The plural members (20) bundled in the aggregating step are, after being softened by heating, elongated in a longitudinal direction thereof in an elongating step, whereby an elongated body is formed. The elongated body formed in the elongating step is cut along a plane perpendicular to the longitudinal direction of the elongated body in a cutting step. By these steps, a planar optical waveguide, on which a waveguide pattern based on a micro-structure is formed, is manufactured.</p>
