摘要：

The application of novel photonic technologies in radio telescope systems becomes more-and-more attractive thanks to the improvement of the performance of photonic signal transport and photonic signal processing technologies and a reduction of their cost level. For the development of photonic technology for radio telescopes like the SKA, a photonic phased array roadmap has been defined at ASTRON, according to which a number of photonic technology demonstrator are built and experimentally investigated. In one of the first steps of the roadmap, a discrete IC component based photonic phased array tile with optical analog links and photonic beamformer was developed. Currently a photonic phased array tile is being built with hybrid integrated optical transmitter and photonic beamformer IC technology. In this paper, the photonic phased array technology roadmap will be described. In addition, a description will be given of both photonic phased array demonstrator systems and experimental results will be given.
