摘要：

The authors report, for the first time, the demonstration of a UV directly written directional coupler in a planar silica waveguide on silicon: From the device parameters and the measured spectral characteristics. the UV-induced index change is calculated to be 0.0075. This is the highest photoinduced refractive index change reported to date in a planar silica waveguide.
