Optical generation of microwave signals
Speaker: Prof. Tibor Berceli, Budapest University of Technology and Economics
When: 2004-09-09 17:00:00
Venue: 78-420
Host: Prof Marek Bialkowski (ITEE)/Dr Ashley Robinson (IEEE)
Abstract:The combination of the optical and microwave techniques offers new
approaches for the generation of microwave signals. That is made
possible by the very high bandwidth of the optical devices and the
very low attenuation of the optical fiber. The advantageous features
for optical generation of microwave signals include ultra wide
tuning range, very low noise, and local oscillator remoting.
In the seminar, principles of generation of microwave signals using
optical means will be described and the advantages of this approach
with respect to microwave communication sub-systems will be
explained. Possible areas of applications of this technique will be
presented.
The seminar will also cover a short presentation on microwave
photonics research activities at the Budapest University of
Technology and Economics. These will include Relative Intensity
Noise (RIN) suppression for microchip lasers, Millimeterwave
oscillator design (20GHz) and Noise Reduction, Nonlinear effects in
digital microwave transmissions, Optical processing of microwave
signals by SOA, FRANS - Fiber Radio ATM Network Services and Packet
Switched Optical Networks.
Biography:Tibor Berceli was born in Budapest, Hungary. He graduated in
electrical engineering at the Technical University of Budapest. He
received the Candidate of Technical Science (Ph.D.), and the Doctor
of Technical Science (D.Sc.) degrees from the Hungarian Academy of
Sciences. At present he is a Professor of Electrical Engineering at
the Technical University of Budapest where he teaches courses on
combined optical-microwave techniques and active nonlinear microwave
circuits.
Professor Bercelli played a key role in organising a number of
microwave and photonics conferences in Europe including the 20th
European Microwave Conference, the 2003 Microwave Photonics
conference in Budapest, and the 1986, 1990, 1999 and 2003 Microcoll
Conferences in Hungary.
He made significant contributions in the field of microwave
photonics and nonlinear microwave circuits, which earned him a
number of national and international awards including an IEEE Fellow
award.
He held a visiting professor position at Polytechnic Institute of
Brooklyn (USA) in 1964, University College London (UK) in 1986,
Drexel University (Philadelphia, USA) in 1988-89, Technical
University of Hamburg-Harburg (Germany) in 1991, Osaka University
(Japan) in 1992, Technical University of Grenoble (France) in 1994
and Helsinki University of Technology (Finland) in 2001.
In 2004, he is a visiting professor at the University of Sydney in
Australia.
