| Abstract(in English) | Using the Mosquito method, the fabrication condition is investigated for multimode optical waveguides with GI circular cores. When a viscous core monomer with a viscosity of 50,000 cPs and higher is dispensed into a cladding monomer layer through a straight needle, a dip is observed in the upper perimeter of the core. Such a core-shape deviation is a concern to degrade the optical properties such as the coupling loss between an optical fiber and the waveguide. In this report, curved needles are introduced in order to form a perfectly circular core, even when a high-viscosity core monomer is dispensed: the dip could be eliminated by varying the dispensing direction of the core monomer. In fact, we evaluate the dependence of the ratio of the vertical to horizontal axes observed in the elliptical cores on the curved angle of needles after experimentally fabricating the waveguides. It is confirmed that an almost circular core shape (without a dip) is formed when the curved angle is in a range of 15-20°. In addition, the optical properties of the waveguides with and without a dip are reported. |
