Trends in photonics and optoelectronics

The final report from the 22nd Telecommunications Educational Seminar focused on Trends in photonics and optoelectronics and related topics held in Slavkov u Brna from the 15th to the 17th of June 2015.

The 22nd Telecommunications Educational Seminar supported by the project "Development of Excellence of the Telecommunication Research Team in Relation to International Cooperation - CZ.1.07/2.3.00/20.0217" was held for three days in Slavkov u Brna in lecture room Golf Hotel Austerlitz from the 15th to the 17th of June 2015.

The first seminar day was opened by Dr. Daniel Benedikovic from University of Zilina (Slovakia) with his lecture entitled Fiber-Chip Couplers for Applications in Silicon Photonics Optical Interconnects. In this talk he evaluated research possibilities of integrated optics in utilization of Fiber-chip edge couplers or Fiber-chip grating couplers. Next lecturer was Ass. prof. Dr. Dana Seyringer from Vorarlberg University of Applied Sciences (Austria). Her presentation was named AWG optical demultiplexers: from design to chip, during this lecture a deeper look into the patterns and processes concerning AWG design from the beginning to chip fabrication were discussed. The third lecturer of the first seminar day was Dr. Libor Ladanyi from University of Zilina (Slovakia). His lecture was entitled New opportunities in all optical networks. Dr. Ladanyi explained during his lecture technique of dispersion control for soliton transmission, usage of nonlinear FBG’s as a switching device and utilization of narrow filters in NG-PON2 networks. Following presentation named Fiber-optic Sensors was given by Dr. Petr Munster from Brno University of Technology. His presentation was dealing with utilization and development of new type distributed sensors for industry. Next lecture was given by prof. Masanori Hanawa from University of Yamanashi (Japan). His presentation was named Sampled Fiber Bragg Grating Based Optical Transversal Filtering and its application to Optical Code Division Multiplexing and was aimed at FBG deployment as a filter for OCDM. Her second talk at our seminar then presented Ass. prof. Dana Seyringer, this lecture was entitled Optical Splitters. Final lecture of the first seminar day had title OCDMA as Data MUX Technique for Optical Broadband and was given by prof. Ivan Glesk from University of Strathclyde (UK). This presentation was oriented at modern application of OCDMA in broadband networks.

The second seminar day was open by second lecture from prof. Glesk, this time his lecture have had title Towards Data Security in Coms. Prof. Glesk explained history and evolution of data security in the telecommunication branch. Then his first lecture named Microwave Photonics & principles and applications was giving prof. Hovik Baghdasaryan from State Engineering University of Armenia. He explained to the attendees what they can imagine under that term and how it can be used in practical applications. Next lecture was given by prof. Gabriele Bolognini from Italian National Research Council. His lecture entitled Distributed optical fiber sensors: trends and applications presented modern methods of optical DTS systems in practical applications. He also provided mode detailed overview of the physical-mathematical background of used principles in these sensory systems. Following lecturer was Dr.

Filip Dvorak from University of Defence with the lecture named Polarization maintaining fiber sensor applications aimed at light polarization state solving in fiber sensors. Contiguous speaker was Dr. Michal Lucki from Czech Technical University in Prague with the presentation entitled Laser ablation - fundamentals, principles. In his talk he described problems connected with laser ablation and its utilization. The last speaker of the second day was prof. Marian Marciniak form National Institute of Telecommunications (Poland) who was giving two consecutive lectures. His first presentation was named Plasmonic Effects in Combined Random and Ordered Silver Nanowires - Rigorous Modeling. It was concerning very perspective method of plasmonic effect in silver nanowires. His second presentation has had title Hybrid Transparent Optical Networking and was dealing with hybrid types of photonic networks and their future development.

The last, third seminar day was opened by Ass. prof. Marc Wuilpart from Université de Mons (Belgium). His lecture named Rayleigh scattering in optical fibres and its application to sensing was introducing principles of Rayleigh scattering in optical fibers used as a sensors. Next lecture was given by prof. Hovik Baghdasaryan and his second talk entitled Surface plasmons - principles and applications introduced theory of surface plasmons in detail. Seminar then continued with second lecture of Ass. prof. Marc Wuilpart, where he was dealing with light polarization state in optical fibers and its possible usage. This lecture has had title Polarization effects in optical fibres and applications. Next to the last presentation was named BPM modeling of integrated optic waveguide structures and radiation field guiding, given by prof. Marian Marciniak. The final lecture entitled Method of Single Expression - alternative approach for boundary problems solution in classical electrodynamics presented by prof. Hovik Baghdasaryan closed whole three days long seminar.

During all seminar days prevails very pleasant and friendly atmosphere, which allows establishing of many new contacts and offers for cooperation. Thanks to presented specialized lectures and demonstration our students and employees had opportunity to take a closer look into the problems in photonics and optoelectronics and related topics.
