Microwave Photonics: Research, Development, and Valorization in University of Twente

RF and photonics are often considered as two separate subfields in electrical engineering. What will happen when they combine their power?

The graduate and the undergraduate program in Electrical Engineering, University of Pelita Harapan would like to kindly invite you for the following guest telelecture session:

This guest telelecture session is open and free for public.  For further information and registration, please contact mte ( dot ) seminar ( di ) staff ( dot ) uph ( dot ) ( edu ) by sending e-mail containing your name, mobile phone number, address, and affiliation.

Abstract

Microwave photonics (MWP), the field that combines the best from the photonic and radio-frequency engineering worlds, has been going from strength to strength in tackling various functions like the generation, distribution, processing and measurements of high frequency signals. In this talk, the microwave photonics research activities in the University of Twente are discussed. The first part of the talk is focused on the development of ultra-high performance microwave photonic links, which are the backbones of any MWP system. Here, the concepts of link gain, noise, linearity and dynamic range are introduced. In the second part of the talk, the development of a large-scale phased-array antenna system based on integrated photonic beamformers is described. The use of fully-programmable integrated photonic chips to process (i.e. to delay and combine) radio signals from a large number of antenna elements are explained. Aspects towards the commercialization of this antenna system, which will be used to provide airline passengers with a live television service from a satellite, are also discussed.

Who is the guest lecturer?

David Marpaung was born in Balikpapan, Indonesia in 1979. He received the B.Sc. degree in physics (with honors) from Institut Teknologi Bandung, Indonesia, in 2002, and the M.Sc. degree in applied physics and the Ph.D. degree in electrical engineering, both from the University of Twente, Enschede, The Netherlands, in 2003 and 2009, respectively. From 2005 to 2009 he was working on his Ph.D. research on performance enhancements of analog photonic links in the Telecommunication Engineering group, University of Twente. From July to October 2008 he was a guest researcher at the Netherlands Foundation for Research in Astronomy (ASTRON) working on gain enhancement and noise figure reduction of externally modulated analog photonic links, which will be used in a large-scale phased array antenna for radio astronomy purposes. He is now working as a postdoctoral researcher in the Telecommunication Engineering group, carrying out research on a large-scale photonic beamformer based on optical ring resonators. Dr. Marpaung is a member of the Photonics Society of the IEEE.
