The generation, manipulation, and transfer of ultrabroad-band signals is essential for the realisation of the internet of things and future quantum networks. Microwave photonics has emerged as a promising field that leverages the benefits of both photonics and microwave technologies. This project focuses on the realisation of photonic integrated circuits that can convert high-frequency signals into optical signals to be, subsequently, transferred via optical fibres. This proposed PhD research aims to develop a comprehensive system-level implementation for the generation of chirped radio waves or microwaves up to THz frequencies through photonic techniques. The research will further focus on integrating this system with on-chip platforms using simulations, followed by device fabrication. The final phase of the research involves applying the photonically generated chirped signals for efficient multi-user transmission, for example in the frequency range of 40 to 50 GHz. The project proposal has been co-created with the Compound Semiconductor Applications Catapult to support the opening of their new Future Telecoms Hub in Bristol in 2023, where part of this project will be based.

超宽带信号的产生、操纵和传输对于物联网和未来量子网络的实现至关重要。微波光子学已成为一个利用光子学和微波技术优点的有前景的领域。该项目的重点是实现光子集成电路，可以将高频信号转换为光信号，然后通过光纤进行传输。这项拟议的博士研究旨在开发一种全面的系统级实现，通过光子技术生成高达太赫兹频率的线性调频无线电波或微波。该研究将进一步侧重于使用模拟将该系统与片上平台集成，然后进行器件制造。研究的最后阶段涉及应用光子生成的线性调频信号进行高效的多用户传输，例如在 40 至 50 GHz 的频率范围内。该项目提案是与化合物半导体应用弹射器共同创建的，以支持 2023 年在布里斯托尔开设新的未来电信中心，该项目的一部分将设在该中心。
