论文摘要
我们在光子BICMOS技术中进行数值和实验剪切的2D光栅耦合器研究，重点是它们的分裂行为。考虑了两种实现波导到颗粒剪切角的形式。用作菜谱的交叉极化被证明很大程度上取决于光栅扰动强度，并且不仅是光栅拆分性能，而且是其耦合效率的关键限制。
We investigate numerically and experimentally sheared 2D grating couplers in a photonic BiCMOS technology with a focus on their splitting behavior. Two realization forms of a waveguide-to-grating shear angle are considered. The cross-polarization used as a figure-of-merit is shown to be strongly dependent on the grating perturbation strength and is a crucial limitation not only for the grating splitting performance, but also for its coupling efficiency.
