采用一种基于波前匹配法的新设计方法，设计了具有稳定分束比的Y分支光波导。所设计的Y形分支采用硅基平面光波电路技术制作。我们在实验上抑制了Y分支分束比的任何变化，在1.3-1.7个/splµ/m的宽波长范围内获得了0.35分贝的额外损耗。
We designed optical Y-branch waveguides with a stabilized splitting ratio by using a new design approach based on the wavefront matching method. The designed Y-branches were fabricated using silica-based planar lightwave circuit technology. We suppressed any variation in the splitting ratio of the Y-branch experimentally and obtained excess losses of <0.35 dB over a wide wavelength range of 1.3-1.7 /spl mu/m.
