在芯片上创建集成空分复用（SDM）的前景，利用多模式波导中的许多引导空间模式的正交自由度，通过增加或替换常用的波分复用（WDM）方法，有望大幅降低联网系统的成本、复杂性和可扩展性。作为SDM方法的演示，我们介绍和实验表征的周期性纳米结构的谐振耦合器集成的多模波导，选择性地传输任意波导模式之间的能量。与其他方案相比，该设备在封装密度、工作带宽控制、可调谐性（以多种正交空间模式工作）以及支持大量交换端口方面具有优势。
The prospect of creating integrated space-division multiplexing (SDM) on a chip, utilizing the orthogonal degrees of freedom of numerous guided spatial modes in a multimode waveguide, promises a substantial reduction in the cost, complexity, and scalability of networking systems by augmenting or replacing the commonly used approach of wavelength-division multiplexing (WDM). As a demonstration of the SDM approach, we introduce and experimentally characterize a periodically nanostructured resonant coupler integrated with a multimode waveguide that selectively transfers energy between arbitrary waveguide modes. Compared to alternative schemes, this device possesses advantages in terms of packing density, control of operating bandwidth, tunability to operate with numerous orthogonal spatial modes, and support of a large number of switching ports.
