Next generation mobile communications networks, such as 6G will revolutionise the way we interact with technology, enabling super high-speed connections to our mobile devices. However, this places incredible strain on the backhaul and access networks that support 5G and beyond. Optical connections are the only viable solution for handling the terabits of data that will be generated by mobile users. Working with the world leading supplier in mobile access technology, this project will develop novel optical systems for supporting ultra-high capacity optical linkages over cable free inter mobile cell connections.In this project, the student will develop a novel and efficient optical multiplexing technique for a form of space division multiplexing called orbital angular momentum (OAM) multiplexing. This form of information encoding puts a twist in the tale of propagating photons, and has potential to massively increase the capacity of communications channels. In the development of this sorter, the student will create new passive optical components based on transformation optical design, that can demultiplex information encoded in OAM with ultralow channel crosstalk. Free-form, metamaterial and diffractive optical systems will be explored. A further critical element of their novel optical designs, will be the support course wavelength division multiplexing (1270nmn to 1610nm), and will be integrated with bespoke adaptive optical solutions for mitigating atmospheric turbulence based on commercial deformable mirror technology. Supported by post-doctoral researchers these novel systems will be manufactured and tests in real-world communication systems.These technologies will have direct application within the research field of optical communications, but will also provide new optical systems that could be used within remote sensing and imaging systems that operate over long-distances. Previously demultiplexers, developed by Dr Lavery, have been widely used globally by world-leading research groups in quantum optics, astronomy, environmental sensing, and optical metrology, where these advanced systems will be fully transferable into these research fields. The student will collaborate with fellow researchers in the Structure Photonics Research group to transition their systems for use in optical sensing and metrology experiments. Further, environment sensing using spatially shaped light has become a recent hot topic, where the advances made within this PhD project will have a considerable impact on this emerging field.

下一代移动的通信网络，如6G，将彻底改变我们与技术的互动方式，实现与我们的移动的设备的超高速连接。然而，这给支持5G及更高版本的回程和接入网络带来了令人难以置信的压力。光连接是处理移动的用户产生的兆兆比特数据的唯一可行的解决方案。本项目将与世界领先的移动的接入技术供应商合作，开发新型的光学系统，以支持无电缆的移动的小区间连接的超高容量光链路。在本项目中，学生将开发一种新型高效的光复用技术，用于称为轨道角动量（OAM）复用的空分复用形式。这种形式的信息编码使光子传播的故事发生了变化，并有可能大规模增加通信信道的容量。在该分类器的开发中，学生将基于转换光学设计创建新的无源光学元件，该元件可以以超低信道串扰解复用OAM编码的信息。自由形式，超材料和衍射光学系统将被探索。他们的新型光学设计的另一个关键要素将是支持波分复用（1270 nm至1610 nm），并将与定制的自适应光学解决方案集成，以减轻基于商业可变形镜技术的大气湍流。在博士后研究人员的支持下，这些新系统将在实际通信系统中进行制造和测试。这些技术将直接应用于光通信研究领域，但也将提供新的光学系统，可用于远距离操作的遥感和成像系统。此前，由Lavery博士开发的解复用器已被全球量子光学、天文学、环境传感和光学计量领域的世界领先研究小组广泛使用，这些先进系统将完全转移到这些研究领域。该学生将与结构光子学研究小组的研究人员合作，将他们的系统转换为用于光学传感和计量实验。此外，使用空间形状光的环境传感已成为最近的热门话题，在这个博士项目中取得的进展将对这个新兴领域产生相当大的影响。
