We demonstrated the fabrication of single-mode optical polymer waveguide using fs-laser direct patterning technique. By using a Ti-Sapphire laser (800nm, 130fs) provided with an achromatic lens and a motorized x-y-z linear stage, polymer waveguide structure was fabricated. The refractive index was easily modified by adjusting the concentration of two kinds of monomer for the core polymers. Subsequently, single-mode propagation from the optical waveguide at 1310nm was realized by confirmed the near field pattern of the coupled light.
