The purpose was to perform an experimental performance evaluation of analogue radio-over-fiber for 5G waveform transport. The results obtained showed a promisingly high performance fronthaul using phase modulation with interferometric detection for the uplink and intensity modulation with direct detection for the downlink. Similar or, in some cases, even better performance was demonstrated for the phase modulated link compared to the intensity modulated one leading to a possible energy efficiency optimisation at the remote unit as the optical phase modulator does not require a bias supply.
- Dr. Salim FACI, an associate professor from Le Conservatoire National des Arts et Métiers, Paris (France), visited Prof. Nathan Gomes and his team in the University of Kent, Canterbury (UK) from 12th to 16th November 2018 with the purpose of evaluation of radio over fiber performances for 5G fronthaul applications based on phase modulation and coherent detection. During this STSM, silicone photonic integrated circuits were defined as a potential solution for such analogue photonic systems. Future collaboration between the two intuitions was engaged on this way.

The purpose of the STSM was to investigate the implementation of backscattering Mobile Terminals (MTs) to an all-photonic FMCW system in order to simultaneously identify and locate the MTs. The experiments were successful and the researchers were able to simultaneously localize and identify the MTs with minimal signal processing power.
- Nada Badraoui, a PhD student from Budapest University (Hungary) travelled to the University of Duisburg-Essen (Germany). The 5G mobile network deployment goal is to provide 1-10 Gb/s wireless signal for the end user. For that purpose, polarization multiplexing (POL-MUX) can be utilized to double the bandwidth efficiency. At these bit rates, the polarization mode dispersion (PMD) becomes very problematic as a bit rate limiting factor. It influences the polarization cross talk and polarization extinction ratio (PER). We propose the application of single side-band Pol-Mux techniques for radio over fibre system achieving this way increased capacity. The performance of the orthogonal coherent polarization multiplexed (Pol-Mux) in a radio over fibre system for multi-user MIMO using linear polarized antennas technique is improved by using polarization beam splitter/combiner and polarization controller with different polarization phase shift, different fibres length, and different bit rate”.
- David Kóbor, from the Budapest University of Technology and Economics in Hungary, spent 6 weeks in the laboratory of Stavros Iezekiel in Nicosia to investigate the recent developments in the field of opto-electronic oscillators.

The aim of the STSM was to design and develop antenna-integrated mm-Wave and THz photonic emitters based on HHI’s PIN-photodiodes. Such devices find applications in multi-Gbps microwave photonic wireless communications systems. Moreover, THz broadband antenna arrays were designed, along with fabrication mask, on HHI’s PolyBoard material, to be used in photonics-enabled phased array emitters for 2D beamsteering. The primary outcome of this research stay is development of first ever WR-03 (J-band) integrated PIN-PD emitter module.
- Andrej Lavric, a PhD student from the Faculty of Electrical Engineering in Ljubljana (Slovenia) visited Photonic Networks & Technologies National Laboratory of CNIT in Pisa (Italy). During the 10 days of visit he performed a characterization of sensitivity, bandwidth, and linearity of house-packaged photodiodes. Photodiodes were successfully used in microwave photonics experiments ranging from optoelectronic oscillator, microwave photonics assisted measurement of phase noise and possible 5G radio access network. Performance of characterized photodiodes showed comparable to commercial solution of laboratory diodes thus making it an attractive cost effective solution for future microwave photonics experiments.
- Luis Vallejo, a PhD student from Instituto de Telecomunicaciones y Aplicaciones Multimedia, Universitat Politecnica de Valencia (Spain), made a stay in Czech Technical University in Prague (Czech Republic), under the supervision of Stanislav Zvanovec, aiming to advance method in microwave photonics, during 35 days.
