Controlled beam splitters for new-generation reconfigurable PONs

Objective
To develop the theoretical model and the software for calculation and optimization of diffractive properties of holographic photonic photopolymer-LC structures with non-uniform layout of electrode structure, enabling interaction of light fields through three-dimensional controlling electric field.

Intended use
Remote control of beam splitting ratio for optimization of reconfigurable PON

Academic novelty
The project offers a more efficient method for control of characteristics of holographic diffractive photopolymer-LC structures that makes it possible to reduce the required voltage as compared to the currently available methods.

Development of the formation method and formation of optically reconfigurable phase elements based on photorefractive lithium niobate crystals for transformation of amplitude profiles of coherent beams

Objective
Experimental and theoretical research and demonstration of formation of optically reconfigurable elements for transformation of amplitude profiles of coherent beams for Fabry-Perot interferometer in lithium niobate (LiNbO3) samples with the surface doped with photorefractive impurities.

Indented use
The elements will help expand the range, reduce the cost and help simplify beam controlling equipment and can be used in laser tool engineering, laser technology, optical data transmission and processing systems, and for engineering of optical sensors and devices. Optically reconfigurable beam converter transforms amplitude profiles by self-action of light fields in lithium niobate crystals and does not require any application of the external controlling field, beam transformation being controlled by light.

Academic novelty
The project makes it possible to expand the dynamic range by using asymmetric power splitters, and offers a new method for device calibration.

Development of the microwave signal RMS meter

Objective
To develop the microwave signal RMS meter with the frequency range of 50 MHz to 8 GHz

Intended use
The device is designed for measurement of the absolute power of the signals propagating via the coaxial feeder. The device can be used as an independent power meter or as an element of measuring benches. Another application is measurement of complex modulated signals, such as Прибор применим для измерений сигналов со сложной модуляцией, таких как GSM-EDGE, CDMA, W-CDMA, WiMAX, LTE.

Academic novelty
The project offers a method to expand the dynamic range by applying asymmetrical power splitters, and a new method for device calibration.
