Mobile data traffic is predicted to grow at very high pace in the next decade. The increase of 5G users (+3.6Bn in 2026), 5G coverage (~60% of the population in 2025), and 5G per-capita speed (x13 in 2023) is challenging the existing mobile transport infrastructures.The new 5G infrastructure will have new and smart radio antenna systems, able to deliver up to 2Gbps to single users with low latency. These will be equipped with multiple radio elements in order to perform massive multiple-in multiple-out functions, together with beam steering/forming. The intra-antenna data process cannot be performed with traditional electric transport and a new approach is needed based on optical data exchange between radio-frequency integrated circuits and digital processors. High bandwidth density, low cost, low power consumption, and outdoor operativity are required for optical transceivers to enable such applications. Existing optical platforms cannot meet all the requirements simultaneously. A new technology is required, capable ofhandling large amounts of data at higher speeds whilst meeting cost per Gbps targets and minimising energy consumption. Graphene is an ideal material for optoelectronic applications. Its photonic properties give several advantages and complementarities over other materials. GIPT will develop a graphene-integrated photonic transceiver to enable the 5G intra-antenna optical connectivity by exploiting the unique properties of graphene. GIPT will demonstrate cost-effective, high-performance, low-power consumption, and temperature resilient, electro absorption modulators and photodetectors, ready to be taken to the next development and commercialisation steps.

预计在未来十年中，移动数据流量将以很高的速度增长。 5G用户（2026年为36亿+36亿），5G覆盖范围（占2025年人口的60％）和5G人均速度（2023年的X13）对现有的移动运输基础架构提出了挑战。新的5G基础设施将拥有新的和智能的无线电系统，能够提供新的和智能的无线电系统，能够为单个使用者提供2GBPS的使用，从而可以提供2GBPS的用户。这些将配备多个无线电元件，以便执行大量的多个多英寸多范围功能以及光束转向/形成。基于传统的电动传输，基于射频集成电路和数字处理器之间的光学数据交换，需要采用新方法进行新方法。光学收发器需要高带宽密度，低成本，低功耗和室外操作性才能实现此类应用。现有的光学平台无法同时满足所有要求。需要一项新技术，能够以较高速度来掌握大量数据，同时每个Gbps目标的会议成本并最大程度地减少能耗。石墨烯是光电应用的理想材料。它的光子性能具有比其他材料的几个优点和互补性。 GIPT将开发石墨烯集成的光子收发器，以利用石墨烯的独特性能来实现5G-Antenna光学连通性。 GIPT将证明具有成本效益，高性能，低功率消耗以及温度弹性，电动吸收调节剂和光电探测器，准备进入下一个开发和商业化步骤。
