Abstract | 1×2 and 2×2 optical waveguide directional couplers were fabricated in a silica glass sample by a femtosecond laser and characterized at the wavelength of 1.5μm. The coupling coefficient was determined by systematically writing series of 1 X 2 directional couplers. After the process and design optimization, the two types of waveguide directional couplers successfully achieved the coupling ratio of about 3.0dB with the average IL and PDL 6.55±0.25dB and 0.28±0.12dB respectively. The multi-scan writing technique with inter-scan shifts was used to reshape the magnitude and profile of the refractive index change so that excess loss of S bends and the PDL for such couplers were substantially reduced. |
