The Research Tasks

Photonics technology is in the process of entering many traditional electronics markets. It started in telecommunications and data centers. More recently it has been spreading to sectors like precision instrumentation, sensing, aerospace, automotive, health-care and defense.  Photonic integration has been revolutionizing optics in the latest two decades in a similar way as integrated circuits revolutionized electronics in some over 50 years ago.

 

Optical industry has been concentrated on the improvement of the properties of single components for a long time, investing a lot in finding the best materials, and refining techniques to obtain various devices. Currently photonics companies produce optical chips using standard fabrication processes and materials to make all kinds of devices.

The successful candidate will join a multinational ad-hoc team, 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] and planar waveguides [2] in Er: TeO2-W2O3 optical glass, using MeV energy nitrogen 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

The ideal candidate must have a good command of everyday and scientific English.  He or she has to be familiar with computer codes for the control and evaluation of experiments, must be willing to continue learning, be laborious, must have his or her own ideas concerning research.
