Recently, the results of researchers in the Graphene Flagship project show that graphene-based integrated photonic devices provide a unique solution for next-generation optical communications. Researchers have demonstrated that graphene can achieve ultra-wideband communication and low power consumption, fundamentally changing the way data is transmitted in optical communication systems. This may make graphene integrated equipment a key factor in the development of 5G, Internet of Things (IoT) and Industry 4.0. The results were published in Nature Reviews Materials and highlighted on the cover.


“As traditional semiconductor technologies are approaching their physical limitations, we need to explore new technologies to achieve our most ambitious vision for a future networked global society,” explains Wolfgang Templ, head of transceiver research at Nokia Bell Labs in Germany. They are one of the flagship partners of Graphene. “Graphene is expected to be an important step in the performance of key components of optical and radio communications, surpassing the performance limits of today's traditional semiconductor component technology.” Nokia IP and optical network technician Paola Galli agrees: “Graphite photonics provides A range of advantages can be a way to change the rules of the game. We need to explore new materials that go beyond the limits of existing technology to meet the future capacity needs network."

Graphene Flagship's latest paper demonstrates the future vision of graphene-based integrated photonics and provides strategies for improving power, manufacturability and wafer level integration. At the same time, Graphene's flagship partners provide a roadmap for graphene-based photonic devices that exceeds the technical requirements for the development of data communications and telecommunications markets driven by 5G, IoT and Industry 4.0. “Graphene integrated in photonic circuits is a low-cost, scalable technology that can run fiber links at very high data rates,” said Marco Romagnoli of Graphene's flagship partner CNIT from the Telecommunications Union of the Italian National Telecommunications Union. .

Antonio D'Errico from Graphenes Flagship partner Ericsson Research explains "The potential of graphene for photonics to change information and communication technologies in a disruptive way. This article was published in Nature Reviews Materials and explains how to enable new features." Rich optical network. I am happy to say that this basic information is now available to anyone interested in the world.

This industrial and academic partnership of companies and research centers in five different European countries has developed a compelling vision for the future of graphene photonic integration. The team involved researchers at CNIT, Ericsson, IMEC, Nokia, Nokia Bell Labs, AMO, ICFO and Cambridge. These collaborations are at the heart of the graphene flagship and were established by the European Commission to support the commercialization of graphene and related materials until 2023. “The graphene flagship is a unique ecosystem, and industrial and academic partners work together for a longer period of time than a normal EU project. This lasting synergy has produced unprecedented results in science and innovation,” Romanooli Commented.

“The collaboration between industry and academia is key to exploring new component technologies. Research at this stage is a significant risk, so it is important that academic research and industry research laboratories join the smartest thinking to solve the underlying problem. Giving perspectives on relevant research issues about future system potential," added Nokia's Bell Labs' Templ. “Because of the exchange of information, we can mature the technology and consider all the requirements for future industrialization and mass production of graphene-based components.”

“This case demonstrates the power of graphene technology in the application of cutting-edge applications in telecommunications. From the transition from material development to component and system-level integration, we have begun to see the results of graphene's flagship investment,” explains Kari Hjelt, head of innovation. . Graphene flagship.

Graphene photonics has advantages in both performance and manufacturing compared to the prior art. Graphene ensures modulation, detection and switching performance to meet all of the next steps in photonic device manufacturing. "Our goal is a highly integrated optical transceiver that will make the ultra-high bit rate of each optical channel exceed 1 terabit per second. These target systems will be achieved by drastically reducing complexity, energy dissipation and form factor. The difference between semiconductor-based front-end systems. Higher flexibility and adjustability," explains Templ.

Daniel Neumaier from Graphene's flagship partner AMO GmbH is also a leader in the flagship division of electronic and photonic integrated graphene, adding: "Optical communication links will become more and more important in 5G to support all nodes needed High data rates. Optical components based on graphene integrated on silicon platforms will provide higher performance and lower cost production processes, and are therefore expected to be key components in the 5G era."

“This paper clearly explains why the integrated approach of graphene and silicon-based photonics can meet and exceed the foreseeable requirements of the ever-increasing data rates in future telecom systems,” said university professor Andrea C. Ferrari. Cambridge, President of Graphene's flagship technology officer and its management team. “The arrival of the Internet of Things and the 5G era provides a unique opportunity for graphene to demonstrate its ultimate potential,” he concludes.

The graphene flagship is one of the largest research projects in the EU. With a budget of 1 billion euros, it is an unprecedented new joint coordination research program. The overall goal of the graphene flagship is to bring graphene and related materials from the academic laboratory to European society, promote economic growth and create new jobs within a decade. Through an alliance of nearly 150 academic and industrial partners, research covers the entire value chain, from material production to component and system integration, to several specific goals that leverage the unique properties of graphene and related materials.
