1	50 GHz optical true time delay beamforming in hybrid optical/mm-wave access networks with multi-core optical fiber distribution显示文摘We propose and experimentally validate an optical true time delay beamforming scheme with straightforward integration into hybrid optical/millimeter(mm)-wave access networks. In the proposed approach, the most complex functions, including the beamforming network, are implemented in a central office, reducing the complexity and cost of remote antenna units. Different cores in a multi-core fiber are used to distribute the modulated signals to high-speed photodetectors acting as heterodyne mixers. The mm-wave carrier frequency is fixed to 50 GHz(VBand), thereby imposing a progressive delay between antenna elements of a few picoseconds. That true time delay is achieved with an accuracy lower than 1 ps and low phase noise.	álvaro Morales Idelfonso Tafur Monroy Fredrik Nordwall Tommi Sφrensen	2018	Chinese Optics Letters2018，16，4：	2
