摘要
对Ge0.4Si0.6/Si超晶格探测器光场进行了分析,并用京传播法(BPM)进行模拟。还探讨了这种探测器与Si波导的集成。在Si波导满足单模传输的条件下,推出光场在探测器中达稳态分布时的传播距离。另外还提出了这种探测器的设计长度与波导尺寸之间的依赖关系。
The optical field in superlattice photodetector Ge0.4Si0.6/Si is analyzed and has been calculated by the Beam Propagation Method(BPM) in this paper. The possibility of integration of a silicon waveguide and this kind of detector is discussed. On condition that single-mode is propagated in waveguides and detectors,the propagation distance, when it reaches stability, can be calculated. In this paper, the photodetector length versus waveguide parameter is also proposed.
