Abstract
A self-written branched optical waveguide is formed. A laser beamfrom a laser source (not shown) is focused with a lensonto the face of incidenceof an optical fiber. The laser beam of an LPmode was emitted from the face of emergence, and 'bimodal' light intensity peaks were arranged in the horizontal direction (.A). A slide glasscoated with a photocurable resin gelwas placed horizontally (.B). A single linear cured materialwas formed as the LP-mode laser beam was emitted from the face of emergenceof the optical fiber(.C). A branch portionwas then formed at a distance L from the face of emergenceof the optical fiber, which was followed by the growth of two cylindrical cured materialsand. The two cylindrical cured materialsandwere linear branches, and formed an angle of about four degrees. An optical waveguidethus formed was composed of cured materials, and(.D).
