摘要：
本文提出一种在绝缘体上硅（SOI）平台上制备1×2功率分束器的新方法，并将所提出模型扩展为1×N系统器件。当前设计策略基于众所周知的简化相干耦合（SCC），该方法允许构建非常尖锐的弯曲。为了分束入射光，我们在分束器入口处加入一个小型多模干涉仪（MMI）。文中分析并讨论了设计参数的敏感性。此外，我们制备并评估了新型分束器架构的1×2和1×4版本，随后将这些器件与在同一SOI光子芯片上实现的、基于标准多模干涉仪（MMI）的分束器进行比较。新型分束方案表现出与标准MMI相近的性能，但在新器件中观察到略为平坦的光谱响应。通过这种新方法，可以设计高度紧凑的器件，因此该策略也为改进和增强在SOI方案下开发的集成器件性能开辟了新途径。
英文摘要：
In this paper, we introduce a new approach to fabricate under the Silicon on Insulator (SOI) platform a 1x2 power splitter and scale it to 1xN system device from the proposed model. The current strategy of design is based on the well-known simplified coherent coupling (SCC) which allows the construction of very sharp bends. To split the incoming light, we add at the entrance of the splitter a small Multi Mode Interferometer (MMI). The sensibility of the design parameters is analyzed and discussed in the paper. In addition, we fabricated and evaluated the new splitter architecture on 1x2 and 1x4 versions and then compared our devices with those splitters based on standard multimode interferometer (MMI) also performed in the same SOI photonic chip. The new splitter scheme shows a similar performance to standard MMI, however, a slight spectral flat response was observed in new devices. By the novel approach, highly compact devices can be designed so this strategy can also open new avenues to improve and enhance the performance of integrated devices developed under the SOI scheme.
