摘要

设计并制作了一种基于SOI的插入损耗非均匀性增强星形耦合器，提高了总透射率。该设计采用“挤压”双输入锥度，辅助输入锥度紧邻中央输入锥度。特殊设计的锥形结构将自由传播区域入口的基本高斯形输入剖面转换为正弦模场，在输出波导阵列处产生平顶远场剖面，而不会增加整个器件的占地面积。

Silicon-based star coupler power splitter with enhanced non-uniformity

We designed and fabricated a SOI based insertion loss non-uniformity enhanced star coupler with improved total transmission. The design utilizes a ‘squeeze’ dual input taper with auxiliary input taper placed right next to the central input taper. The specially designed taper structure transforms the fundamental Gaussian-shaped input profile at the entry of the free propagation region into a sinc mode field which produces a flat-top far field profile at the output waveguides array, without adding to the overall device footprint.
