Innovative high-performance bulk, thin film and nanocomposite materials for electro- and nonlinear-optical devices in micro- and nanoelectronics.

Project content

Task of project:

A significant increase in the efficiency of electro-optical and nonlinear-optical sensitive elements, resulting in recommendations for the use of appropriate materials in optical radiation control devices with characteristics that will exceed those of world analogues.

Object and subject of research:

Bulk crystals of lithium niobate, strontium borate, and langasite for electro-optical studies were oriented relative to the crystallographic axes; samples of straight and X/45o sections were prepared, which were checked for deviations from the given orientation using a polarizing optical microscope. The electro-optical coefficients were studied using a Mach-Zehnder interferometer. Thin films of ZnO doped with Sn are particularly intriguing, given its relevance in the development of integrated nonlinear optics devices.

The purpose and main objectives of the study:

The goal of the project is to search for and create materials to ensure greater efficiency of electro-optical light beam control devices and nonlinear optics devices by using optimal spatial orientation of the active elements of the devices and/or technological approaches that will improve the properties of known active media (in particular, nanomatrices filled with crystalline material or liquid crystal with optimal spatial orientation of nanocrystallites); it is also planned to prove the effectiveness of a new effect - the diffraction electro-optical effect.

Main tasks of the project:

The main results

  1. A technology for manufacturing nanocomposites based on nanoscale matrices has been developed. Samples of Al2O3 and SiO2 membranes filled with KB5 crystallites have been obtained. X-ray structural studies have shown that synthesized crystalline KB5 and LiNbO3 were found in the SiO2 and Si matrices
  2. The setup for nonlinear optical (NO) studies was modified. The second harmonic generation (SHG) in nanocomposites Al2O3:Pt+OEP (platinum-octaethyl-porphyrin) and Al2O3:Hel+Ni (helicate with Ni2+ cations), as well as in lithium niobate crystals LiNbO3, was studied depending on the polarization direction of the SHG signal and the angle of rotation of the sample.The second- and third-order nonlinear optical properties of composite thin films based on europium (Eu) and gadolinium (Gd) and polymethyl methacrylate (PMMA) have been studied. It has been found that these composites have good nonlinear optical properties. A modified method of extreme surfaces has been tested to determine possible directions of phase synchronism in crystals
  3. A setup for studying the electro-optic (EO) effect based on a Mach-Zehnder interferometer was created. Initial values ​​of the absolute EO coefficients of the model crystal LiNbO3 were obtained, which perfectly coincide with the literature data
  4. A modified method and appropriate equipment for the synthesis and study of an anti-reflective material have been developed. It has been shown that the material (with a low reflectance in a wide spectral range) is a nanoporous Al2O3 matrix with ammonium dihydrogen phosphate (ADP, NH4H2PO4) crystals embedded in it

Originality and innovative aspects

The dependences of the EO efficiency on the diffraction order for different geometries of the diffractive EOE in langasite crystals with a periodic change in the refractive index in the sample volume were obtained for the first time.

The results of the work have practical value, which is determined by the prospects for their use in the field of developing light beam control devices and generating coherent optical radiation of various frequencies. The creation of such devices with optimized operating characteristics will allow to significantly improve existing scientific, applied, military or industrial optical systems, in particular, to increase the efficiency of electromagnetic radiation modulation in information transmission systems. A number of areas for further implementation have a dual purpose, as the results of the project can be effectively used in military telecommunications systems, optical infrared ranging, information protection, transmission and processing systems, or be used as an anti-reflective coating for military equipment. Work on creating such materials is being carried out as part of the project.

According to the project materials the oral and poster presentations were made at international conferences
