Tapered Transitions for Integrated Optics - Analytical Study

高速、大容量光通信系统将拥有与单模光纤连接的集成光学或光电子电路和设备。集成光学中的锥形跃迁对于改善不同尺寸的集成光学器件以及集成光学器件和单模光纤之间的互连损耗具有重要意义。现有的微扰技术将被扩展到分析非对称波导中阶跃不连续处的辐射损失。这一分析工作将足够普遍，不仅可以考虑波导锥度，而且还可以考虑轴向不均匀，如折射率和宽度变化以及波导中的弯曲。

High speed, high capacity optical communication systems will possess integrated optical or optoelectronic circuits and devices connected to single mode optical fibers. Tapered transitions in integrated optics are important for improving interconnect losses between integrated optical devices of different dimensions as well as integrated optical devices and single mode fibers. Existing perturbation techniques will be extended to analyze radiation losses at step discontinuities in asymmetrical waveguides. This analytical work will be general enough to accommodate not only waveguide tapers but also axial inhomogeneities such as index and width variations as well as bends in the wave guides.
