 Session 1:  Integrated Photonic Devices for Data Communications

08:35-09:00
Graphene integrated photonics for next generation optical communications

Marco Romagnoli, National Laboratory for Photonics Networks, CNIT

Graphene provides a new possible solution for future integrated photonics, it exhibits electro-absorption, electro-refraction effects that can be used for ultra-fast modulation and photo-thermoelectric effect for photodetection. High index contrast integrated photonics devices and circuits can be realized with small footprint and low power consumption.

Over the past few years, significant progress has been made in graphene photonics and optoelectronics and large improvements are still possible and under consideration. In this perspective, we present the vision and advantages of graphene-based integrated photonics for data communication and we will show strategies for wafer scale integration.


09:00-09:20
Graphene-based photonics - enabler for future broadband communication solutions?

Wolfgang Templ, Ph.D., Alcatel-Lucent Bell Labs

In the "internet era" modern communication technologies increasingly penetrate our daily life and have significant influence on our way of daily living and our society. This is going along with an ever stronger increasing data traffic - on individual, and global scale. Future communication system solutions need to provide extreme high data rates up to the range of 10's of Gbit/s down to the user - ideally ubiquitous and at any time. Keeping this in mind today's hardware solutions based on semiconductor technologies are by far too expensive and inefficient when considering commercial applications in the access network down to the individual user. In this situation Graphene based photonic solutions may promise a way out. The talk will discuss several challenges and how Graphene could help us to find a way out.


09:20-09:40
Integrated graphene photonics: from electronic physics to photonic functionalities

Tingyi Gu, Princeton University

The broadband optical response and excellent electrical conductivity sets a unique role for the single layer graphene in chip-scale systems. Integrating graphene into matured complementary metal-oxide semiconductor devices brings a low-cost pathway for producing active photonic devices on silicon. In conjunction with nanostructured semiconductor materials, single layer graphene hybrid devices are proven to elevate electronic performance with minimum perturbation to photonic designs. In this talk, I will present our recent progresses of graphene-silicon optoelectronics, including all-optical nonlinearities and photodetectors.


09:40-10:00
Photodetection using 2D materials

Klaas-Jan Tielrooij, ICFO-Institut de Ciencies Fotoniques, The Barcelona Institute of Science and Technology

Graphene and related 2D materials offer the possibility of thin, flexible, cost-effective photodetectors that can easily be integrated with existing technologies. Owing to the special material characteristics and unconventional physical mechanisms that lead to the photoresponse, 2D-material-based detectors have already been demonstrated for a large range of wavelengths (from the UV to THz), with picosecond response times and with competitive efficiencies. This talk will discuss photodetection using the photo-thermoelectric and photo-thermionic effect, which are both simultaneously ultra-broadband and ultrafast, and will outline different avenues for improving detector performance.

 Session 2: IR and THz Applications in Detection and Sensing

10:50-11:15
THz detection with graphene and CNT field-effect transistors

Prof. Dr. Hartmut G. Roskos, Physikalisches Institut, Goethe-Universität

Antenna-coupled field-effect transistors (Tera-FETs) are versatile and sensitive detectors of THz radiation useable from the MHz regime up to at least 10 THz. We have investigated Tera-FETs in four different material systems, silicon CMOS, AlGaN/GaN, CVD graphene and carbon nanotubes. A comparative performance analysis will be presented. Special attention will then be given to two aspects. The carbon devices have hitherto unexploited potential with respect to their high Fermi velocity which may allow to reach the ultra-sensitive ballistic regime of device operation; and they exhibit a pronounced thermal behavior which adds a significant thermoelectric contribution to the signal.


11:15-11:35
Graphene-based thermal detectors for infrared imaging

Alan Colli, Nokia Technologies, Cambridge, UK

Detecting thermal infrared radiation in the 5-14 um range is becoming increasingly important for applications in healthcare, smart energy systems, security, fire sensing, automotive, and motion tracking. For practical applications at room temperature, thermal photodetector devices such as bolometers have emerged as the technology of choice. I will present and discuss a new class of thermal detectors that combine graphene and pyroelectric materials to achieve very large sensitivities. Tiny temperature differences (~10-100 uK) induced by the absorption of thermal photons (~6-10 um) can be resolved in ambient conditions.


11:35-12:00
2-D materials for transparent electrodes and mid-IR sensing

Valerio Pruneri, ICFO-The Institute of Photonic Sciences and ICREA

In the talk I will show how ultrathin metals of a thickness ranging from 0.5 to 50 nm can be used to directly grow graphene on transparent substrates. Appropriate combinations of ultrathin metals, graphene and other transparent conducting materials have been used to achieve transparent electrodes which have similar electro-optical performance as ITO and, at the same time, are mechanically flexible. Other 2-D materials can also be directly grown on dielectrics for providing new functionalities, including mid-infrared plasmonic sensing of molecules.


12:00-12:20
Non-linear optical excitation of surface plasmons in graphene

Dr. Tom Constant, University of Exeter, UK

We present recent optical wave-mixing measurements showing the excitation of surface plasmons in planar graphene. A large enhancement of non-linear signal in regions of high density of states suggests a strong coupling to propagating plasmons in graphene for a variety of in-plane wave-vectors. Estimates regarding the non-linearity of graphene and the efficiency of the DFG process are inferred from our experiment. These results demonstrate a promising route to efficient generation of surface plasmons in graphene using free-space radiation.


12:20-12:45
Two-dimensional materials and heterostructures as a novel platform for optoelectronics

Ilya Goykhman, Cambridge Graphene Centre, Department of Engineering,  University of Cambridge, UK

The emerging field of two-dimensional (2D) materials provides an exciting opportunity to explore novel technological paradigms in photonics and optoelectronics. The richness of optical and electronic properties of 2D materials and versatility of van der Waals heterostructures allow new approaches for designing advanced optoelectronic devices and functionalities across a wide range of electromagnetic spectrum.  In this talk, I will discuss Si-graphene detectors for integration in silicon photonics and explore van der Waals heterostructures for flexible and light emission applications.  Key aspects related to device physics, material properties, fabrication process development and system performances will be discussed.

 Session 3: Wafer Scale Processing and Integration

14:00-14:20
Development of a 200 mm wafer graphene technology platform

Grzegorz Lupina, IHP, Leibniz-Institut fuer innovative Mikroelektronik

Development of a wafer-scale Si technology-compatible graphene synthesis method and a toolbox of processes dedicated to handling/cleaning as well as deposition of semiconductors and insulators on graphene is considered as a prerequisite to practical applications of this material in electronic and photonic devices. In this talk, we outline how these challenges are addressed to enable fabrication of graphene devices in a 200 mm Si wafer pilot line at IHP.


14:20-14:40
The challenges and opportunities of CMOS compatible integration of 2D materials for photonics technology

Cedric Huyghebaert,IMEC

Until now, 2D material based applications have been demonstrated in different semiconductor fields. These promising results have received a lot of attention, but none of them has resulted yet in a 2D material technology embraced by the semiconductor industry. The field of optical interconnects is a candidate to force such a breakthrough. Silicon photonics provides broad bandwidths with very low optical absorption; it has been successfully implemented in low-loss optical waveguides and other passive components. However, other semiconductors like Ge or III-Vs are required to produce high-performance active components, such as light sources, modulators and photo detectors. Recent extensive research has demonstrated graphene photo detectors and graphene modulators co-integrated with Si waveguides with high efficiency and speed in a broad range of wavelengths. Nevertheless these devices were processed with a typical lab integration scheme. This talk will outline the research on the 2D materials family. Imec is exploring integration schemes for silicon photonics transceiver incorporating graphene-based modulators and photodetectors co-integrated with silicon waveguides, whose main focus is to provide an answer to the question of whether the family of 2D materials could really hold the promises for a successful use in silicon photonics and as an extension in microelectronics in general. This is being accomplished with a strategy encompassing two main aspects of research: (1)to evaluate novel device concepts based on the fundamental properties of 2D materials (2) to work towards industrial compatible solutions for 2D material integration in a semiconductor environment.


14:40-15:05
Ultrahigh-mobility graphene devices from chemical vapor deposition on reusable copper

Christoph Stampfer, RWTH Aachen University

Graphene research has prospered impressively in the past few years, and promising applications such as high-frequency transistors, magnetic field sensors, and flexible optoelectronics are just waiting for a scalable and cost efficient fabrication technology to produce high-mobility graphene. We show that the quality of CVD-grown graphene depends critically on the used transfer process, and we report on an advanced transfer technique that allows both reusing the copper substrate of the CVD growth and making devices with carrier mobilities as high as three millions cm2/(Vs).
