Graphene is ideal for opto-electronics due to its high carrier mobility at room temperature, electrically tuneable optical conductivity, and wavelength independent absorption. Graphene has opened a floodgate for many layered materials (LMs). For a given LM, the range of properties and applications can be tuned by varying the number of layers and their relative orientation. LM heterostructures (LMHs) with tailored properties can be created by stacking different layers. The number of bulk materials that can be exfoliated runs in the thousands, but few have been studied to date. The layered materials research foundry (LMRF) will develop a fully integrated LM-Silicon Photonics platform, serving 5G, 6G and quantum communications, facilitating new design concepts that unlock new performance levels. Graphene and the other non-graphene LMs are at two different stages of development. Graphene is more mature, and can now target functionalities beyond the state of the art in technologically relevant devices. In (opto-)electronics, photonics and sensors, graphene-based systems have already demonstrated extraordinary performance, with reduced power consumption, or photodetectors (PDs) with hyperspectral range for applications such as autonomous driving, where fast data exchange is a critical requisite for safe operation. Applications in light detection and ranging, security, ultrasensitive physical and chemical sensors for industrial, environmental and medical technologies are beginning to emerge and offer great promise. These technologies must be developed to achieve full industrial impact. The other non-graphene LMs are also at the centre of an ever increasing research effort as a new platform for quantum technology. They have already shown their potential, ranging from scalable components, such as quantum light sources, photon detectors and nanoscale sensors, to enabling new materials discovery within the broader field of quantum simulations. The challenge is understanding and tailoring the excitonic properties and the nature of the single photon emission process, as well as to make working integrated devices. Quantum emitters in LMs hold potential in terms of scalability, miniaturisation, integration with other systems and an extra quantum degree of freedom: the valley pseudospin. A major challenge is to go beyond lab demonstrators and show that LMs can achieve technological potential. The LMRF will accelerate this by enabling users to fabricate their devices in a scalable manner, with comparable technology to large-scale manufacturing foundries. This scalability is essential for LMs to become a disruptive technology. The vision is to combine the best of Silicon Photonics with LM-based optoelectronics, addressing key drawbacks of current platforms. ICT systems are the fastest growing consumers of electricity worldwide. Due to limitations set by current CMOS technology, energy efficiency reaches fundamental limits. LM-based optoelectronics builds on the optical/electronic integration ability of Silicon Photonics, which benefits product costs, but with modulator designs simpler than conventional Silicon Photonics at high data rates, giving lower power consumption.

石墨烯非常适合光电，由于其在室温，可调的光导率和波长独立吸收的高载流子迁移率，因此是理想的。石墨烯为许多分层材料（LMS）打开了闸门。对于给定的LM，可以通过改变层数及其相对方向来调整属性和应用的范围。可以通过堆叠不同的层来创建具有定制特性的LM异质结构（LMHS）。可以在成千上万的批量运行中可以去角质材料的数量，但迄今为止很少有人研究。 分层材料研究铸造厂（LMRF）将开发完全集成的LM-Silicon光子水平平台，为5G，6G和量子通信提供服务，从而促进新的设计概念，以解锁新的性能水平。石墨烯和其他非透明烯LM处于开发的两个不同阶段。石墨烯更加成熟，现在可以针对技术相关设备中最新技术的功能。在（光学）电子，光子学和传感器中，基于石墨烯的系统已经表现出非凡的性能，功耗降低或光电探测器（PDS）（PDS），用于应用程序（例如自动驾驶）的高光范围，其中快速数据交换是安全操作的关键必要条件。在光检测和范围内的应用，安全性，超敏化物理和化学传感器，用于工业，环境和医疗技术，开始出现并提供了巨大的希望。必须开发这些技术以实现全面的工业影响。作为量子技术的新平台，其他非磷酸LMS也是越来越多的研究工作的中心。他们已经显示出潜力，从可扩展的组件（例如量子光源，光子检测器和纳米级传感器）到在量子模拟的较宽领域内发现新材料的发现。挑战是理解和调整单个光子发射过程的激子特性以及制造工作集成设备的性质。 LMS中的量子发射器在可伸缩性，微型化，与其他系统的整合以及额外的量子自由度方面具有潜力：山谷伪一种。一个主要的挑战是超越实验室示威者，并表明LM可以发挥技术潜力。 LMRF将通过使用户能够以可扩展的方式制造其设备，并具有与大规模制造铸造厂相当的技术来加速此设备。这种可扩展性对于LMS成为一项破坏性技术至关重要。愿景是将最佳的硅光子学与基于LM的光电子学相结合，以解决当前平台的关键缺点。 ICT系统是全球增长最快的电力消费者。由于当前CMOS技术设定的限制，能源效率达到了基本限制。基于LM的光电学基于硅光子学的光学/电子整合能力，从而使产品成本受益，但调制器设计比传统的硅光子学以高数据速率更简单，从而提供较低的功率消耗。
