We developed a novel waveguide fabrication technology, i.e., femtosecond (fs) pulse laser assisted self-writing waveguide technology, to overcome problems of standard technologies, such as time consuming and high cost. Based on a light induced self-written (LISW) waveguide fabrication technology, a 488nm cw laser was launched through an optical fiber into UV curable resin. At the same time a 800nm fs laser was additionally used as a 3D position selective assistant beam. As the UV resin was cured by the 488nm laser and 800nm fs laser irradiation, a fiber/waveguide connecting 2D/3D waveguide was easily fabricated.
