Big Data & Analytics, Cloud, Mobile and Social Management are currently driving business innovation by making organizations more collaborative, virtual, adaptive, agile to responding to market demands. Consequently, mega data centers containing tens of thousands of computers have been growing rapidly and demanding high-speed optical communication systems for solving bottlenecks in large-scale clusters. Silicon-based coherent optical communication systems offer a great potential of meeting the market needs. The advantageous properties of silicon platforms in telecommunication such as low-loss transmission and CMOS-compatibility for low-cost opto-electronic integration make silicon platforms extremely attractive. The central building block in coherent optical communication systems is an optical waveguide-based 90° hybrid for demodulating optical signals. In this proposed work, we utilize a wedge-shaped 2 × 4 MMI coupler butt-coupled with a 2 × 2 MMI coupler. This structure in silicon photonics platform is well suited for a broadband optical 90° hybrid with a compact device footprint. The ultimate goal of this research is to lead to a commercially viable product.

大数据和分析、云、移动的和社会管理目前正在推动业务创新，使组织更具协作性、虚拟性、自适应性和敏捷性，以响应市场需求。因此，包含数万台计算机的巨型数据中心一直在快速增长，并需要高速光通信系统来解决大规模集群中的瓶颈问题。硅基相干光通信系统具有巨大的市场潜力。硅平台在电信中的有利特性，如低损耗传输和低成本光电集成的CMOS兼容性，使硅平台极具吸引力。相干光通信系统中的中心构建块是用于解调光信号的基于光波导的90°混合器。在这项工作中，我们利用一个楔形的2 × 4 MMI耦合器对接耦合的2 × 2 MMI耦合器。硅光子平台中的这种结构非常适合于具有紧凑器件占地面积的宽带光学90°混合。这项研究的最终目标是产生一种商业上可行的产品。
