A téma rövid leírása, a megoldandó legfontosabb feladatok felsorolása: Design, fabrication and characterization of integrated optical elements and circuits for telecommunication and optical biosensors using ion beam techniques Ph.D. work in Physics BUDAPEST UNIVERSITY OF TECHNOLOGY AND ECONOMICS, Budapest, Hungary Institute: Wigner Research Centre for Physics, Budapest, Hungary
The successful candidate will join a multinational (Hungarian, Italian and Sapnish) ad-hoc team, performing performing research work to develop a novel technology for photonic integrated circuit fabrication using only ion beam implantation and irradiation techniques. Intensive researches in this field began in 2004. Some of the most important results obtained so far are: Fabrication of channel waveguides [1,3] and planar waveguides [2] in Er: TeO2-W2O3 optical glass, using MeV energy nitrogen and carbon ion implantation. The Ph.D. student will have the possibility to participate in the implantation/irradiation of the new samples at the new ion nanobeam line of the MTA Atomki Research Centre (Debrecen, Hungary), as well as in the Tandetron Laboratory of the Řež Nuclear Research Institute (Czech Republic). His or her main research tasks will be the design and the optical and functional characterizations of the integrated optical elements and circuits, using the following techniques: - Classical microscopy (interference, phase contrast, INTERPHAKO, DIC) - M-line spectroscopy (using a METRICON 2010M Prism Coupler) - Spectroscopic ellipsometry - Micro Raman spectroscopy - Ionoluminescence
