Scientific research laboratory (SRL-109) was created in 2005 as a part of the Telecommunication department from the European Union funding of Ukrainian Science and Technology Center in Ukraine (STCU) project №3222 "Spatial anisotropy complete 3D-analysis in geometry optimizations of electro-, piezo- and acousto-optic interactions (new computer aided design of highly efficient optical modulators and deflectors)" (2005-2007 , project manager Andrushchak A.S.) and was further developed form the funds of the project STCU №4584 "Development of most efficient acoustooptic cell creation methodology for super-high-frequency control of powerful laser radiation "(2008 - 2010) as well as the Ukrainian- Polish project №М/138-2009 (2009-2010 ) and Grant of the President of Ukraine funded by Ministry of Education and Science of Ukraine (GP/F56/167).

In 2010, Professor Andrushchak A.S. won an international grant and became the coordinator of the European project №272715 "New production technology development for most efficient and more stable application of electro-optic and nonlinear optical crystalline materials " of the Program FP7-PEOPLE-2010-IIF, which was successfully implemented initially in Czestochowa Polytechnic (Poland, 2011-2013), and then finished in the Lviv Polytechnic National University (return phase, 2013-2014).

In 2017, Professor Andrushchak A.S. and his research team won another international grant MSCA-RISE-2017-IMAGE №778156 of the European Program "Horizon 2020" (https://project-image.eu), in which the Ukrainian organization (Lviv Polytechnic National University) under the leadership of the project leader Andrushchak A.S. became the principal coordinator of such type of grants (for the first time in Ukraine), uniting 9 European institutions. For the successful implementation of this project on the basis of SRL-109 in 2018, the Center of Excellence for Innovative Technologies and NanoEngineering (CE ITNE) was created, where the international project IMAGE №778156 continues to successfully implemented now at the Department of Applied Physics and Nanomaterial Science (PFN) and such research and training laboratories have been created:

• Laboratory of optical innovative technologies;
• Laboratory of nonlinear-optical and magneto-optical research;
• Laboratory of acoustic and acousto-optical measurements;
• Laboratory of parametric optics and spectroscopy;
• Laboratory of growth research and nanoengineering materials.

It should be noted that in recent years the state budget projects (SBP) SBP/Anisotropy (2016-2018, registration number №0116U004136) and SBP/Modulator (2017-2019, №117U004847) together with project of young scientists SBP/Nanocomposite (2016-2018, №0116U004412) were successfully completed on the basis of the created laboratories of RTC ITNE. Now state budget projects SBP/Nanocrystallite (2019-2021, №0119U002255) and SBP/Optima (2020-2022, №0120U00####) are being performed together with the current project of young scientists SBP/SubTera (2019-2021, №0119U100609). For more details on each of the above projects, see the "Projects" section of this site.

Based on the above mentioned projects in the laboratories of CE ITNE the experimental equipment for optical and quasioptical applied research was created, namely:

• equipment for mechanical cutting and optical processing of required crystalline samples to determine their mass, density and signs of crystal physical coordinate system based on the piezoelectric method;
• technological setup for quality and geometry control of samples processing from crystalline materials by means of conoscopic and interferometric methods;
• automated optical and quasi-optical setups and special software for measuring the refractive indices of plane-parallel samples of isotropic and anisotropic materials in the visible sub-terahertz spectral diapasons;
• acoustic setup for measuring the velocity of longitudinal and transverse sound waves in anisotropic crystals of different symmetry classes using dynamic echo- pulse method with subsequent calculation of piezoelectric and elastic coefficients;
• interferometric (based on a Michelson interferometer) and polarization- optical setup and developed own methodology to determine all tensor components for electro-optical effect in crystalline materials of arbitrary symmetry class;
• interferometric (based on Mach-Zehnder interferometer) and polarization- optical setups and developed own methodology to determine all the components of the tensors of elastic and piezo- optic effect in crystalline materials of all classes of symmetry;
• acousto-optical setup for measuring the quality of acousto-optical crystal materials using Dixon-Cohen method;
• experimental setup for measurements of nonlinear optical parameters of materials by the Z-scan method and the method of Maker fringles;
• personal computers and existing specific software for automation of the measurements and to perform all necessary calculations.

On available in the laboratory equipment all necessary basic and applied research for piezo- , elastic- , electro-, acousto- and nonlinear optical effects in crystalline materials of all classes of symmetry can be made for more efficient use of these materials as working elements of corresponding devices for controlling or converting laser radiation. An experimental base for the development and fabrication of a new class of crystalline nanocomposites with tailored anisotropy based on nanoporous Al2O3 or Si/SiO2 matrices and various water-soluble crystalline materials was created in the Laboratory of growth research and nanoengineering materials.

The team members of CE ITNE have a proven track records on these topics: more than 200 scientific and technical papers and 15 patents , 2 Doctor of Science and 4 PhD dissertations, has published over 110 abstracts at national and international conferences and symposia. Also, a textbook approved by the Ministry of Education, Youth and Sports of Ukraine was published (letter of 22.07.2011 № 1/11-6547 est.): Applied Electrodynamics of Information Systems: a textbook / A.S.
