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.

石墨烯是光电子学的理想材料，因为它在室温下具有高的载流子迁移率，电学可调的光学导电性，以及与波长无关的吸收。石墨烯为许多层状材料(LMS)打开了闸门。对于给定的LM，可以通过改变层的数量和它们的相对取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LMHS。可以剥离的散装材料的数量数以千计，但到目前为止，很少有人对其进行研究。分层材料研究代工厂(LMRF)将开发一个完全集成的LM-Silicon Photonics平台，服务于5G、6G和量子通信，促进新的设计理念，释放新的性能水平。石墨烯和其他非石墨烯LMS处于两个不同的发展阶段。石墨烯更加成熟，现在可以在技术相关的设备中实现超出最先进水平的功能。在(光电)电子学、光子学和传感器领域，基于石墨烯的系统已经显示出非凡的性能，具有更低的功耗，或者具有高光谱范围的光电探测器(PD)，用于自动驾驶等应用，在这些应用中，快速的数据交换是安全运行的关键条件。在光检测和测距、安全、工业、环境和医疗技术的超灵敏物理和化学传感器方面的应用开始出现，并提供了巨大的前景。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，其他非石墨烯LMS也处于日益增长的研究努力的中心。它们已经展示了自己的潜力，从可扩展的组件，如量子光源、光子探测器和纳米传感器，到在更广泛的量子模拟领域内发现新材料。挑战是理解和定制激子特性和单光子发射过程的本质，以及制造工作的集成器件。LMS中的量子发射器在可伸缩性、微型化、与其他系统的集成以及额外的量子自由度方面具有潜力：山谷赝旋。一个主要的挑战是超越实验室演示，并证明LMS可以实现技术潜力。LMRF将加快这一进程，使用户能够以可扩展的方式制造他们的设备，使用可与大型制造铸造厂相媲美的技术。这种可伸缩性对于LMS成为一项颠覆性技术至关重要。我们的愿景是将硅光子学的精华与基于光子学的光电子学相结合，解决当前平台的主要缺陷。信息和通信技术系统是全球增长最快的电力消费者。由于当前cmos工艺的限制，能效达到了基本极限。基于LM的光电子学建立在Silicon Photonics的光学/电子集成能力基础上，这有利于产品成本，但调制器设计在高数据速率下比传统Silicon Photonics更简单，从而提供更低的功耗。
