In physics, biology and engineering the bandwidths of the signals to analyse steadily increase. According to the Cisco Visual Networking Index Forecast, the number of devices connected to the internet will be three times the global population in 2022, for instance. Correspondingly, the global internet traffic will increase threefold over the next five years. Worldwide crisis like Covid-19 have additionally pushed the data rates in the networks with a dramatic shift from business centers to residential areas. The increasing data-rates raise the demands on the electrical signal processing and measurement in the global communication networks. Current solutions that rely on electronics are limited by inefficient energy consumption and heat dissipation. In this project, we develop alternative schemes for the measuring of high-bandwidth signals that are based on Photonics: silicon devices that process light waves instead of electronics. Photonics solutions enable ultra-high bandwidth signal measurement and they are immune against electromagnetic interference. We look to combine between photonic devices and mature electronics technology to achieve complete signal measurement solutions, supporting the demands of tomorrow. Specific research objectives include integrated devices for the measurement of ultrahigh-bandwidth signals in the time- and frequency domains with twice the sampling rate of current cutting-edge electronic oscilloscopes and a resolution one order of magnitude higher than current optical spectrometers. These methods will pave the way to small-footprint, low-cost measurement chips, which are able to monitor and measure bandwidths in the THz range for different application fields in physics, biology and engineering including sensing, spectroscopy and communications.

在物理学，生物学和工程学中，信号的带宽以稳步分析。根据Cisco Visual网络指数的预测，例如，连接到Internet的设备的数量将是2022年全球人口的三倍。相应地，全球互联网流量将在未来五年内增加三倍。像Covid-19这样的全球危机还将网络中的数据速率从商业中心转移到居民区，并推动了网络中的数据速率。增加的数据率提高了全球通信网络中电信号处理和测量的需求。依赖电子产品的当前解决方案受到效率低下的能耗和散热的限制。在这个项目中，我们开发了基于光子学的高带宽信号的替代方案：处理光波而不是电子设备的硅设备。光子溶液可以实现超高的带宽信号测量，并且可以免疫电磁干扰。我们希望在光子设备和成熟的电子技术之间结合使用，以实现完整的信号测量解决方案，以支持明天的需求。特定的研究目标包括用于测量超高带宽信号的集成设备，其时间域和频域中具有两倍的采样速率，是当前尖端电子示波器的采样率，并且分辨率比电流光谱仪高一个数量级。这些方法将为小英尺打印，低成本测量芯片铺平道路，这些芯片能够在THZ范围内监测和测量物理，生物学和工程领域的不同应用领域的带宽，包括感应，光谱和通信。
