Dynamically tunable, low-noise, discrete-time optical processing of high-speed signals

在当今社会中，不断增长的带宽需求是不可阻挡的。因此，提供能够对高速信号进行最佳调节的系统就成为一项挑战。许多系统不仅携带所需的信息，而且还携带高电平干扰信号。需要可调的干扰缓解来主动处理不同的干扰，同时对通带的影响最小。本课题研制的新型动态可调谐光子信号处理器在科学、商业和安全等领域具有重要的应用价值。研究结果广泛应用于增强光纤馈电分布式天线系统，在射电天文学和国防雷达系统领域具有国家利益。

In today's society there is an unrelenting push for increasing bandwidth requirements. Thus the challenge arises to provide systems that can optimally condition high-speed signals. Many systems carry not only the desired information but also high level interference signals. Tunable interference mitigation is required to address different interferers actively while having minimal impact on the passband. The new dynamically tunable photonic signal processors in this project have important applications for science, business and security services. The results have widespread uses in enhancing fibre-fed distributed antenna systems, with national benefits in the fields of radioastronomy and radar systems in defence.
