　　摘要: 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 beamformers 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.

　　报告人简介：José Capmany (S’88, M’92, SM '96, F '08) was born in Madrid, Spain, on December 15 1962. He holds a PhD in Electrical Engineering from UPM and a PhD in Quantum Physics from the Universidad de Vigo. Since 2002, he is the Director of the Institute of Telecommunications and Multimedia (iTEAM) at the Universidad Politécnica de Valencia (www.iteam.upv.es). His research activities and interests cover a wide range of subjects related to optical communications including microwave photonics, integrated optics, optical signal processing, fiber Bragg gratings, and more recently quantum cryptography and quantum information processing using photonics. Prof. 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.
