Research fellow.

O. Aktas is a postdoctoral research fellow within the Optoelectronics Research Centre (ORC) at the University of Southampton. He obtained his BSc (1st Honor) in Electrical and Electronics Engineering in 2005 from the Ankara University (Turkey) and then worked as a military engineer in the Turkish Aviation Industry for 10 years. During this period, he earned his MSc and PhD in Physics from the Bilkent University (Turkey) in 2008 and 2014, respectively. In his PhD thesis, he developed a new top-to-bottom nanotechnology fabrication method based on fiber drawing of chalcogenides, and demonstrated photonic applications for photoconductive nanowires, optical microcavity WGM resonators and tapered fibers. He published several articles in top ranked journals in the fields of Material Science, Nanotechnology, Physics and Photonics.

Research

Research interests

He is currently interested in semiconductor core fibers for nonlinear optics applications, and in laser processing of semiconductor materials for photonic and optoelectronic applications.

Teaching

Physics, photonics, semiconductor physics.
