Graphene shows promise for high-speed optical communications

Researchers affiliated with the Graphene Flagship have demonstrated novel high-speed graphene-based data communication at a data rate of 50 Gb/s. Integrating graphene sheets into silicon photonics could form the basis for next-generation data communications.

The project was a collaboration between Flagship partners AMO GmbH (Germany), the National Inter-University Consortium for Telecommunications (CNIT) (Italy), Ericsson (Sweden), Ghent University (Belgium), the Institute of Photonic Sciences (ICFO) (Spain), imec (Belgium), Nokia (Germany and Italy), the Vienna University of Technology (TU Wien) (Austria) and the University of Cambridge (UK).

Mitsubishi Electric is developing graphene-based super-wideband image sensor

The Advanced Technology R&D Center of Mitsubishi Electric Corp. is reportedly developing a graphene-enhanced image sensor that can sense a wide frequency band of light from visible light to terahertz waves with one device.

It is said to be a multi-spectrum image sensor with a lower cost and higher performance, compared with existing multi-spectrum image sensors. Currently, multiple kinds of image sensors are combined in accordance with wavelength to realize a multi-spectrum image sensor, and high-cost materials and liquid nitrogen-based cooling are necessary to detect lights other than visible light.

Impressions from the 2018 Graphene Week in San Sebastian

The Graphene-Info team attended this year's Graphene Week, organized by the Graphene Flagship in San Sebastian, Spain, 10-14 September 2018. The event attracted over 600 visitors from all over the world, and was extremely well organized.

While the talks and lectures were clearly scientifically-oriented, the commercial angle was also evident and many institutes and companies were there to show their recent product advancements. The Graphene Flagship's booth held a fascinating array of exhibits: graphene-enhanced retina and neural prosthesis (biomedical devices) by the ICN2 as a part of Braincom, Airbus' graphene composite for the leading edge of the tail of the Airbus A350, Nokia, Ericsson and AMO's graphene-based modulators and photodetectors for optical communications, a prosthetic robotic hand enhanced with graphene nerve sensors by the IIT, University of Cambridge's insole graphene-based pressure sensor and more.

Researchers affiliated with the Graphene Flagship have shown that integrated graphene-based photonic devices offer a unique solution for the next generation of optical communications. Researchers in the initiative have demonstrated how properties of graphene enable ultra-wide bandwidth communications coupled with low power consumption to radically change the way data is transmitted across the optical communications systems. This could make graphene-integrated devices the key ingredient in the evolution of 5G, the Internet-of-Things (IoT), and Industry 4.0.

"As conventional semiconductor technologies are approaching their physical limitations we need to explore entirely new technologies to realize our most ambitious visions of a future networked global society," explains Wolfgang Templ, Department Head of Transceiver Research at Nokia Bell Labs in Germany, which is a Graphene Flagship partner. "Graphene promises a significant step in performance of key components for optical and radio communications beyond the performance limits of today's conventional semiconductor-based component technologies." Paola Galli, Nokia IP and Optical networks Member of Technical Staff, agrees: "Graphene photonics offer a combination of advantages to become the game changer. We need to explore new materials to go beyond the limits of current technologies and meet the capacity needs of future networks."

The Graphene Flagship moves towards new stage

The Graphene Flagship was launched in 2013 with the mission to take graphene and related layered materials from academic laboratories to the market, revolutionize multiple industries and create economic growth and new jobs in Europe. Five years later, the Flagship consortium has reported that it successfully completed the Core1 phase and is progressing towards more applied phases. It is reportedly on its way to achieving its objective of developing the high potential of graphene and related 2D materials to the point of having a dramatic impact on multiple industries.

The Reviewing Panel thoroughly examined the results obtained in this Core1 phase and concluded that for many topics, there has been a clear transformation of the activities, moving from individual research projects to genuine collaboration towards larger goals – exactly what a Flagship project should aim for. Nearly all milestones and key performance indicators have been met, often exceeding expectations. There are numerous examples of significant scientific and/or technological achievements, with clear progress beyond the state of the art. The Work package on Photonics and Optoelectronics led by ICREA Prof. at ICFO Frank Koppens was recognized as one of the closest to being brought into industrial exploitation due to its significant potential for both scientific breakthrough and innovation.
