Yılmaz Uçar received his bachelor’s degree in Electronics and Communications Engineering from Doğuş University, Turkey, and his master’s degree in Telecommunications Engineering from Universitat Politècnica de Catalunya (UPC-BarcelonaTech), Spain, with the specialization in Antennas, Microwaves and Photonics for Communications and Earth Observation. His master’s thesis was about designing and testing of microwave circuits for optimized R-o-F data transmission which was awarded by Most honorable (MH) title. Moreover, his research paper is in preparation process which presents a novel approach of Optical Single Sideband (OSSB) modulation based on different electrical phase shifts using a dual-drive Mach–Zehnder modulator to support the connections in Passive Optical Networks (PONs) for tunable working frequency without re-adjustment.
