Paper Abstract

We report on a curved waveguide fabrication using femtosecond laser processing with a glass hologram. We design and produce a glass hologram that transforms femtosecond laser beam into a half-ring beam. The half-ring beam generated by the glass hologram is patterned inside fused silica with one laser shot. The guided light whose bending radius is larger than 1mm is observed at wavelength of 635nm. As a simple application, a directional coupler consisting of a straight-line waveguide and a half-ring waveguide is fabricated by two laser shots. Its basic functionality as a coupler is confirmed. We also develop a hologram that simultaneously produces a straight-line and a half-ring. Using it, we demonstrate a directional coupler fabrication inside crown glass with one laser shot.
