合成金刚石膜可以通过使用化学气相沉积（CVD）在诸如硅或二氧化硅的合适基底上以晶片规模制备。虽然这种薄膜在热管理、X射线和太赫兹窗口设计以及回旋管和微波传输线中有着丰富的应用，但它们在纳米级光学元件中的应用在很大程度上尚未开发。在这里，我们证明了CVD金刚石提供了一个高品质的模板，实现纳米光子集成光学电路。利用部分刻蚀金刚石薄膜制备的高效光栅耦合器件，我们研究了毫米级光路，实现了通信波长的单模波导。我们的研究结果为在恶劣环境和可见光器件中进行传感的宽带光学应用铺平了道路。
Synthetic diamond films can be prepared on a waferscale by using chemical vapour deposition (CVD) on suitable substrates such as silicon or silicon dioxide. While such films find a wealth of applications in thermal management, in X-ray and terahertz window design, and in gyrotron tubes and microwave transmission lines, their use for nanoscale optical components remains largely unexplored. Here we demonstrate that CVD diamond provides a high-quality template for realizing nanophotonic integrated optical circuits. Using efficient grating coupling devices prepared from partially etched diamond thin films, we investigate millimetre-sized optical circuits and achieve single-mode waveguiding at telecoms wavelengths. Our results pave the way towards broadband optical applications for sensing in harsh environments and visible photonic devices.
