The last decade has witnessed an incredible increase of Internet traffic that has spurred a rapid evolution of optical communication technology for higher data transmission capacity. Digital signal processing (DSP) has enabled coherent optical communications with advanced modulation formats, which led to giant leaps of single-channel data rates in long-haul transport networks. Next-generation fiber-optic communication systems will have a dramatically increased complexity that cannot be achieved using discrete optical components. Photonic integrated circuits are the most promising solution to the dilemma of scaling system complexity while reducing cost per bit/s. Further advances for future ultra-high-capacity optical transmission systems require synchronized development of integrated photonic devices and DSP algorithms will enable dramatically improved performance and higher power efficiency for ultra-high capacity optical transmission systems. It this project, we will examine high-quality coherent signal generation applying advanced DSP algorithms to significantly improve the state of the art of integrated coherent optical transmitters.

过去十年见证了互联网流量的惊人增长，这刺激了光通信技术的快速发展，以获得更高的数据传输容量。数字信号处理（DSP）使先进调制格式的相干光通信成为可能，这导致了长途传输网络中单通道数据速率的巨大飞跃。下一代光纤通信系统的复杂性将急剧增加，这是使用分立光学元件无法实现的。在降低每比特/秒成本的同时，光子集成电路是解决系统复杂性问题最有前途的方法。未来超高容量光传输系统的进一步发展需要同步开发集成光子器件和DSP算法，这将极大地改善超高容量光传输系统的性能和更高的功率效率。在这个项目中，我们将研究应用先进的DSP算法产生高质量的相干信号，以显着提高集成相干光发射机的技术水平。
