From Datacom to IoT - Enabled by Graphene
2 March 9:30-16:00
Mobile World Congress 2017, Barcelona Spain
Session 1: Data Communication
Graphene enabled optical and wireless Datacom for 5G and beyondDaniel Neumaier, Head of the Graphene group at AMO GmbH
The outstanding electronic and electro-optical properties of Graphene make it a perfect material for high-performance modulators, photodetectors and receivers, meeting the demands of future optical and wireless communication systems in terms of bandwidth, energy consumption and on-chip CMOS-integration. This talk will discuss the opportunities of graphene based electronic and opto-electronic devices, focusing on on-chip photonic components and receiver circuits operating at frequencies up to 100 GHz. A critical assessment with competing technologies will be given.
Graphene photonic Devices in Telecom and Datacom Applications
Paola Galli, Member of Technical Staff at Nokia-Bell Labs
The strong demand for transmission bandwidth at low cost to face the growing 5G mobile communications market and the development of IoT, requires a new technology that overcomes the well-established ones in which costs and performance scaling are limited.
The presentation will address applications in future telecom and datacom markets in which Graphene could play a role as rule breaker and provide low cost, energy efficient photonics devices.
Demonstration of high Speed Data-link based on Graphene
Marco Romagnoli, Head of Advanced Technologies for Photonic Integration at CNIT
Datacom and Telecom require continuous improvement in bandwidth at constant level of consumption and cost reduction. According to the Ethernet roadmap the bandwidth doubles every two years and the candidate technology for large volume and reduced cost must scale on all of these key aspects.
In this presentation we show the roadmap towards graphene integrated photonics devices with very high performances. We report on first transmission experiments on 100km of standard fiber at 1550nm carried out with graphene electroabsorption modulation at 10Gb/s showed performances comparable with well-established technologies. These results indicate the potentiality of scalability of graphene photonics.
Session 2: Flexible Displays and Wearables
Perspective of wearable, flexible and printed Electronics
Henrik Sandberg, Principal scientist at VTT's centre for Printable and Hybrid Functionalities
Graphene and related two dimensional materials (GRMs) are particularly suitable for applications in flexible devices. The GRMs can withstand repeated bending down to very small curvatures, can be applied using a wide variety of methods and onto almost any substrate material. Furthermore, GRMs offer a versatile platform for highly sensitive and selective sensors through their diverse functionalization potential. Thus, both printed low end electronic applications and high performance devices based on grown GRM can be achieved. Wearable applications benefit from those unique GRM properties as devices can be made lightweight, thin, flexible, and potentially even stretchable. Utilizing printed electronics and hybrid integration manufacturing methods devices could also be very low cost – further boosting the strongly expanding wearable electronics market.
Industry Perspective: Bringing Surfaces to Life: The Potential of Graphene and graphene-like Materials for flexible Electronics
Rouzet Agaiby, Senior Business Development Engineer at FlexEnable
Graphene and other 2D materials possess inherent unique properties that, if fully utilised in electronic devices, can prove to be transformational. Graphene’s excellent electronic characteristics make it a suitable contender to replace ITO to develop truly flexible OLED displays. On the other hand, the promising semiconducting properties of other 2D materials like molybdenum disulphide can replace conventional silicon technology to enable high performance flexible devices. The talk will address the challenges associated with maintaining the inherent properties of graphene and 2D materials as they are integrated into the device stack as well as challenges related to scalability in order to transfer the technology from lab to fab.
Session 3: IoT and Sensors
Seeing the Invisible: Sensors and Cameras for Health, Night Vision, Automotive, etc.
Frank Koppens, Group leader at the Institute of Photonic Sciences (ICFO)
There is a large demand for sensors that can be easily integrated with many different objects. The rising trend of the internet-of-things illustrates the need for sensing by any object surrounding us. Sensors should be cheap, invisible and easy to integrate with many different surfaces such as bendable plastic, fabric and glass. And they should “see” thing we cannot see. Here we present a novel sensor platform that does just that.
Application examples include wearable health and fitness monitors that are flexible and ultra-thin as well as low-cost CMOS night vision cameras.
Industry Perspective: High Performance Graphene Sensors - Routes to CMOS Integration
Tapani Ryhänen, CEO and Co-Founder of Emberion Oy
Graphene charge transducers enable a variety of sensors and photodetectors when combined with other chemically-, optically- or physically-sensitized materials. Emberion, a newly-formed SME, employs such graphene photonics and electronics to produce infrared photodetectors and thermal sensors. In this presentation, we discuss the principles of graphene sensors and their performance, the use of graphene in the context of complex CMOS circuitry and finally, Emberion’s vision and focused mission to commercialize graphene photonics. Key applications and customer value are discussed.
