Yilmaz Ucar, M.Sc. – Low phase noise photonic THz sources (ESR 14)

Researcher: Yilmaz Ucar

Research organization: Microwave Photonics GmbH

Researcher CV: 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. 

Research objectives:  This research is aimed at developing new optical methods and processes for developing photonic integrated low phase noise reference oscillator chips. The research also aims at locking those photonic reference oscillator chips with optical heterodyne generators for low phase noise photonic THz generators. This technology platform will be beneficial for applications including THz communications and material sciences such as THz scattering spectroscopy.

Expected results: This research activity is aimed at developing an optically-mediated low phase noise THz source to expand the application field of THz Photonics to communications, material sciences, and spectroscopy. Work in this activity will contribute to the expansion of non-destructive material testing for material characterization and identification in the THz domain as well as for THz imaging and THz communications. This research work will contribute to answering TERAOPTICS’ research Challenges II, III and V.

Planned secondment(s):

  • to UDE (Prof. Andreas Stöhr), M24 for ~ 1.5 months, for THz spectroscopy and THz communications measurements
  • to UCL (Prof. Cyril Renaud), M30 for ~1 months on THz spectroscopy measurements
