Over the past decade, we have witnessed an incredible increase of Internet growth (greater than 40% per year) driven by millions of new users and numerous emerging on-line applications such as Google, Facebook, Youtube, Twitter, Amazon, etc. This expansion would be impossible without the physical support of high-speed optical communications. As the Internet continues its explosive growth, more complex optical systems are needed to provide higher data transmission rates, indicating dramatically increased costs and difficulties in implementation. To solve this dilemma, we are developing nanometer-scale optical devices that allow us to integrate a large number of optical functions on a single chip. Owing to their extremely small footprints and high-level integration, ultra-high-speed optical signals can be generated with minimized cost and power consumption. In particular, these devices are based on silicon, a material on which billions of microelectronic chips have been fabricated. This is exciting because of the great potential to leverage the most sophisticated manufacturing facilities, which are already established for microelectronics, to scale complexity of optical communication systems. This research, if successful, may revolutionize telecommunications, leading to giant leaps of Internet speed.

在过去的十年中，我们目睹了在数百万新用户和众多新兴在线应用程序（例如 Google、Facebook、Youtube、Twitter、Amazon 等）的推动下，互联网增长令人难以置信（每年超过 40%）。如果没有高速光通信的物理支持，这种扩展是不可能的。随着互联网持续爆炸性增长，需要更复杂的光学系统来提供更高的数据传输速率，这意味着成本和实施难度急剧增加。为了解决这个困境，我们正在开发纳米级光学器件，使我们能够在单个芯片上集成大量光学功能。由于其极小的占地面积和高集成度，可以以最小的成本和功耗生成超高速光信号。特别是，这些设备基于硅，数十亿个微电子芯片都是在硅材料上制造的。这是令人兴奋的，因为利用已经为微电子建立的最先进的制造设施来扩展光通信系统的复杂性具有巨大的潜力。这项研究如果成功，可能会彻底改变电信业，导致互联网速度的巨大飞跃。
