Ultrafast Photonic Signal Processing

我们的现代社会在很大程度上依赖于以信号处理为基础的复杂和无处不在的信息和通信技术(信通技术)基础设施。然而，目前信号处理电路中的电子瓶颈从根本上损害了我们在高速电信、信息处理和计算系统中以更低的成本面对不断增长的更高容量的需求的能力。拟议的CRC计划将直接解决这一关键和具有挑战性的问题，目标是开发能够提供所需实用性能的光子信号处理技术，在优化能源效率和减少占用空间方面，而不牺牲其固有的带宽优势。这项研究将直接有助于克服信息和通信技术目前的电子瓶颈，也将有助于满足以环境友好的方式提高能力的迫切需求。这是确保我们的信息和通信技术基础设施的长期可持续性及其所有相关社会经济效益的关键。

Our modern societies heavily depend on a sophisticated and ubiquitous Information and Communication Technologies (ICTs) infrastructure underpinned by signal processing. However, present electronic bottlenecks in signal-processing circuits fundamentally compromise our capability to face the ever-increasing demand for higher capacity at a lower cost in high-speed telecommunications, information processing and computing systems. The proposed CRC program will directly address this critical and challenging problem by targeting the development of photonic signal-processing technologies that can offer the needed practical performance, in terms of optimized energy efficiency and reduced footprint, without trading their intrinsic bandwidth advantage. This research will directly contribute to overcome present electronic bottlenecks in ICTs, and it will also help in fulfilling the pressing demands for increased capacity in an environmentally friendly fashion. This is key to ensure the long-term sustainability of our ICT infrastructure, and all its associated socio-economic benefits.
