PHOTONICS (from the Photonics Dictionary)

The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and information processing.

The main activity field of the department is the development of non-destructive characterisation methods and the R&D on integrated photonic systems.
2013 activities:
 In an international collaboration (Hungary-Japan-Czech) neutron irradiated reactor vessel steel samples were non-destructively analysed. They have proven that the Magnetic Adaptive Test (MAT) developed at MFA is compared to the alternative solutions superior both in regard to sensitivity and reliability as well. Using this technique the remaining lifetime can be assessed reliably.
- In the frame of the EU FP7 (Ultra-versatile Nanoparticle Integration into Organized Nanoclusters, UNION) project spherical as well as nanoparticles possessing shape and surface chemical anisometry were prepared and analysed. Using these particles as construction elements their controlled aggregation will be studied.
- Novel methods were elaborated for the connection of the particles according to a predetermined configuration via the exchange-potential between the particles and their modification upon external stimuli, e.g. into a form of a gold-nanoparticle necklace in the periodic lattice.
- Using domestic and international project support the prototype of their patented (USA, EU, Japan) imaging ellipsometric equipment „Industrial thin-film optical mapping tool” for „record size” 30 - 45cm diameter Si wafers, as well as for thin-film samples of the size of 60 - 90 cm will be developed.
- Within one year (between March 2013 and March 2014) they held eight invited lecture at international conferences about the so called wide-angle ellipsometry and its application as in-line inspection tool for the continuous (roll-to-roll) solar-cell fabrication.
