Mehmet Alp Ilgaz, a PhD student from the University of Ljubljana (Slovenia), received an ITC Conference Grant from this Action for participating in the 2nd International Conference on Photonics Research (Interphotonics 2019), held at the Mirage Park Resort Hotel in Antalya (Turkey) between November 4th to 9th, 2019. He had an invited talk about “Current state of the development of the opto-electronic oscillator “. He described his research about opto-electronic oscillator (OEO) and its implementation in Radio Access Network (RAN). The topic is mainly focused on the OEO and its benefits to microwave photonics and how OEO producing microwave and millimeter wave signals with a very-low phase noise. He also described the advantages of the OEO on the photonic integrated chip and its possible implementation in RAN.
