It doesn't always have to be fiber - fast internet via Hybrid Fiber-Wireless
Surfing the Internet at ultra-high speed - this is what has been enabled by the worldwide fiber network. However, expansion is progressing at a slug speed, also in Germany and especially in the country side. Unfortunately, laying fibers in the ground is time consuming and expensive. But there is hope: a new photonic antenna unit provides the same speed by radio and can be installed in a few days. It has now been successfully tested in the network of a European telecom company. The antenna was developed by the Optoelectronics department at University of Duisburg-Essen (UDE).
From 19th until 21st of September, University of Duisburg-Essen exhibits Coherent Radio-over-Fiber (CRoF) systems for next generation
optical access and mobile networks. The CRoF systems developed within the IPHOBAC-NG project
provide a Wireless Extension of GPON and WDM-PON networks.
Plenary Talk and Symposium on Integrated Photonics
On the occasion of the “International Year Of Light” and the 25th anniversary of the Optoelectronics department, this year’s position of the Scientist in Residence will be held by one of the most recognized international experts in the field of photonics, Professor John E. Bowers.
Within the framework of European research projects IPHOBAC-NG and RAPID 5G new technologies
and system architectures have been developed that allow a particularly efficient radio
transmission even at highest frequencies.
Rattana Chuenchom, currently enrolled at the University of Duisburg-Essen as PhD Student, has presented a new coherent photonic
mixer (CPX) that enables the upconversion of optical baseband signals transparently into the millimeter-wave frequency range by
The characterization of complex materials and moving objects in an arbritrary environment is a key challenge to sensor technology (eg for 3D material maps). For such complex tasks novel sensors need to be developed that adaptively canadjust the waveform, frequency bandwidth, carrier frequency and observation sector to the measurement environment and material properties.
The mobile Internet of the future is unimaginable 50 times more powerful than the current systems and is transmitted via small antennas,
hanging in street lamps and are connected via the fiber optic network with each other..
A Selfie at a rock concert or comparing prices via Internet during sale? Actually, no problem - but too many phones in one place slow down the cellular network.
Researchers at the University of Duisburg-Essen are working on the next generation of mobile communications: 5G.
Radio technologies for 5G using Advanced Photonic Infrastructure for Dense user environments
At the beginning of the year, the European Union and Japanjointly had published a call for collaborative research projects in four specially
selected technology areas. Within the four main priorities, only one project should be encouraged. University of Duisburg-Essen could prevail
with its international partners in the subject "Access Networks for Densely Located User Areas".
Photonics industry needs about 9,000 academically qualified young professionals by 2015
The global photonics market was around 350 billion Euros in 2011
- compared to 228 billion Euros in 2005. The photonics industry has grown each year with an average of around 7.5% in nominal terms, which is more than twice as fast as the worldwide GDP.
Online Master's program in Electrical Engineering and Information Technology
Winter term 2014/15 is coming - best time for new resolutions. How about giving a new impetus to your career? The Electrical
Engineering Department at University of Duisburg-Essen has a clear idea of how it might look
like. It offers an online Master's program: freshly designed, in part-time, and with four majors.
To see the World Cup in full HD live on your tablet or phone, that's a scenario of which fans can only dream of in 2014.
Technologies that can transmit such vast amounts of data by radio are still missing. But we are working on that.
Because more and more work is done with mobile phones, wireless networks need to transfer huge amounts of data.
The Department of Optoelectronics at UDE showcases at the Laser fair in Munich its super-fast 70 GHz radio transmitter with fiber optic connection.
Ivan Flammia, currently enrolled at the University of Duisburg-Essen as PhD Student within the Marie-Curie initial training network "MITEPHO",
has presented a novel grounded coplanar waveguide (GCPW) to substrate integrated waveguide (SIW) transition for the development of compact and cost-effective 60 GHz photonic transmitters,
key elements of Radio-over-Fiber (RoF) systems. For that he received two awards.
Ivan Flammia, currently enrolled at the University of Duisburg-Essen as PhD Student within the Marie-Curie initial
training network “MITEPHO” (MIcrowave and TErahertz PHOtonics), has presented a new photonic transmitter concept
for E-Band (60-90 GHz) Radio-over-Fibre systems, allowing for low-cost integration of optical components (photodiodes)
and radiofrequency elements (high-gain horn antenna) and introducing the possibility of cost-effective hermetic
packaging without the need of sealing plates or radomes.
Japan's National Institute of Information and Communications Technologies (NICT) in Toyko and the Center for
Semiconductor Technology and Optoelectronics (ZHO) have agreed to sign a Memorandum of Understanding on
cooperation in the field of wireless ultra-high speed communications for the mobile Internet access.
Andrzej Jankowski and Ivan Flammia, currently enrolled as PhD researchers at the Institute of Optoelectronics at University of Duisburg-Essen,
have participated this year in the Marie Curie Actions Conference 2012, as part of the Euro Science Open Forum convention (10th -15th July, Dublin).
EU photonic wireless project develops state-of-the-art high speed photodiodes
Wireless transmission in the E-band based on optoelectronic technology has already demonstrated data
rates up to 12.5 Gb/s with On-Off modulation schemes, and reaching up to 27 Gb/s with spectrally efficient
modulation techniques. One of the most promising carrier generation methods is photomixing two optical
wavelengths on a high speed photodiode, which in combination with injection and phase locking techniques
can generate tuneable, high power, narrow linewidth millimetre carrier wave signals. The photodiode is
a key component in these systems, being the element where the optical signals are converted to the
electrical domain. Uni-Traveling Carrier Photodiodes (UTC-PDs) have been the dominant type of photodiodes
for these applications due to their wide bandwidth and high millimetre-wave output power levels.
