论文摘要
这项工作调查了Fabry-Perot Ge-On-Si激光器的较小信号性能，通过建模和仿真。研究了对结构参数的3DB带宽依赖性，例如poly-si覆层厚度，GE腔宽度和厚度以及少数载体寿命。在GE激光结构优化的偏置电流中，在偏置为270.5 mA处的33.94 GHz的3DB带宽以缺陷有限的载体寿命为1 ns。
This work investigated the small signal performance of Fabry-Perot Ge-on-Si lasers by modeling and simulations. The 3dB bandwidth dependence on the structure parameters such as poly-Si cladding thickness, Ge cavity width and thickness, and minority carrier lifetime were studied. A 3dB bandwidth of 33.94 GHz at a biasing current of 270.5 mA is predicted after Ge laser structure optimization with a defect limited carrier lifetime of 1 ns.
