摘要：
We present the fabrication of three-dimensional waveguide structures indide fused silica using the femtosecond laser direct-writing technique. The guiding properties of a produced 1 x 3 splitter are studied in detail. By appropriate choice of the processing parameters a multimode entrance port can be generated which allows to vary the splitting ratio by changing the input coupling. The processing requirements for such splitter devices will-be discussed.
