New coherent photonic mixer for millimeter-wave wireless systems
Best overall paper prize awarded to Rattana Chuenchom
Microwave Photonics is an inter-disciplinary field which covers the interactions between microwave and optical waves for the generation, processing, control and distribution of microwave, millimetre-wave and THz signals. Microwave photonics technologies can find many applications such as in high-speed wireless communications networks, radar, sensors, and modern instrumentation.
The International Topical Meeting on Microwave Photonics (MWP) is the premier international meeting on micro- an millimeterwave photonis and provides a forum for the presentation of new advances in this multi-disciplinary research area, ranging from novel devices to systems field trials.
The location of MWP rotates on a triennial basis among Europe, the Americas and Asia-Pacific region and was held this year, from October 26th to 29th, in Pathos, Cyprus.
Five researchers from University of Duisburg-Essen went to Cypus this year: Rattana Chuenchom, Maria Freire, Vitaly Rymanov, Professor Xihua Zou and Professor Andreas Stöhr (chair of the MWP Technical Programme Committee). They presented work carried out in the past months by the Optoelectronics department in both device and system development.
Particular recognition has been awarded to the work done on the development of new devices for wireless telecommunication applications, for which the "Best Overall Paper Award" was granted to Rattana CHuenchom for her paper entitled "Integrated 110 GHz Coherent Photonic Mixer for CRoF Mobile Backhaul Links".
The presented photonic mixer (CPX) is a joint development of the University of Duisburg-Essen and Finisar. This CPX enables to upconvert optical baseband signals transparently into the millimeter-wave frequency range by optical means. The carrier frequency of the generated radio signal can be tuned in an enormously wide frequency range from DC to 110 GHz . So far, the CPX is suitable not only for today's wireless networks such as 3G, 4G, but also for future 5G networks and even for research networks that operate at even higher carrier frequencies. Other applications are seen in materials analysis and radar technology. This work has been carried out with financial support by the European Commission under the IPHOBAC-NG and RAPID-5G project contracts.
