We experimentally demonstrate that the Mosquito method is capable of fabricating single-mode polymer optical waveguides with multiple cores while maintaining an identical mode-field diameter among them. The we developed a technique to form circular in using commercially available microdispenser and multi-axis syringe scanning robot. However, core shape tends deteriorate from circle because monomer flow due needle scan. also both theoretically for first time this paper needles tapered outer or just titled straight enable high circularity even if those are dispensed on any heights substrate surface.
