20 December 2004One-to-four optical waveguide power splitters fabricated in fused silica glass using a femtosecond laser
1x4 optical waveguide power splitters were fabricated in a fused silica glass sample using a focused 800nm-amplified femtosecond laser, and characterized in terms of their optical properties at the wavelength of 1550nm. A shifted multi-scan writing technique was developed to substantially reduce the excess loss of the involved Y junctions and the polarization dependent loss of such integrated splitters.
