IEEE Photonics Society Distinguished Lecturer 2013/14

José Capmany

ITEAM Research Institute, Universidad Politecnica de Valencia



For the last 25 years, Microwave Photonics (MWP) systems and links have relied almost exclusively on discrete optoelectronic devices and standard optical fibers and fiber‐based components which have been employed to support several functionalities like RF signal generation, distribution, processing and analysis. These configurations are bulky, expensive and power‐consuming while lacking in flexibility. A second generation, termed as Integrated Microwave Photonics (IMWP) which aims at the incorporation of MWP components/subsystems in photonic circuits, is crucial for the implementation of both low‐cost and advanced analog optical front‐ends and, thus, instrumental to achieve these targets. After reviewing the basic principles of microwave photonics (MWP) for the non‐specialized technical audience, this lecture states the case for the integrated approach towards MWP and overviews the available technology platforms (InP, silicon, silica, silicon nitride, chalcogenides etc.) for the implementation of MWP photonic integrated circuits (PICs), outlining the main features advantages and limitations for each one. The lecture then reviews the salient research results reported during the last years in several applications and the different platforms (MWP link, signal processing and filtering, signal generation, delay lines, phase‐shifters and beam-formers etc.) and finally introduces the concept of the MWP transistor, a multipurpose signal processor architecture which allows for the implementation of all the main basic MWP functionalities. The lecture is concluded with a summary and considerations on the future directions of this field.



José Capmany (S’88, M’92, SM ‘96, F ‘08) from Madrid, Spain, received the Ingeniero de Telecomunicacion degree from the Universidad Politécnica de Madrid (UPM) in 1987 and the Licenciado en Ciencias Físicas in 2009. He holds a PhD in Electrical Engineering from UPM and a PhD in Quantum Physics from the Universidad de Vigo. Since 1991 he has been in the Departamento de Comunicaciones, Universidad Politecnica de Valencia (UPV), where he founded the Optical Communications Group ( He has been a Full Professor in optical communications, systems, and networks since 1996. In parallel, he was Telecommunications Engineering Faculty Vice‐Dean from 1991 to 1996, and Deputy Head of the Communications Department since 1996. Since 2002, he has been Director of the Institute of Telecommunications and Multimedia (iTEAM) at UPV ( His research interests cover a wide range of subjects related to optical communications including microwave photonics, integrated optics, optical signal processing, fiber Bragg gratings, and quantum cryptography and quantum information processing using photonics. He has published over 450 papers in international refereed journals and conferences and has been a member of the Technical Program Committees for several major conferences. Professor Capmany has also carried out activities related to professional bodies and is the Founder and current Chairman of the IPS Spanish Chapter, a Fellow of the Optical Society of America (OSA) and the Institution of Electrical Engineers (IEE). He is founder and chief innovation officer of VLC Photonics ( dedicated to the design of photonic integrated circuits. Professor Capmany is the 2012 King James I Prize Laureate on novel technologies, the highest scientific distinction in Spain, for his outstanding contributions to the field of microwave photonics.
