Tapered Transitions for Integrated Optics - Analytical Study

高速、大容量光通信系统将具备 集成光学或光电电路和器件， 单模光纤 集成光学中的锥形过渡 对于改善集成电路之间的互连损耗是重要的 不同尺寸的光学器件以及集成光学器件 设备和单模光纤。 现有的扰动技术将 可以扩展到分析辐射损失的步骤不连续性， 不对称波导 这种分析工作将是足够一般的 为了不仅适应波导锥形而且适应轴向不均匀性 例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.
