Optical Technologies and Telecommunication Systems
In recent works an alternative method for design of silica GeO2-doped graded-index multimode optical fibers 50/125
with low differential mode delay (DMD) was introduced. It is based on synthesis of special refractive index profile,
providing the equalization of guided mode group velocities. A theoretical approbation of introduced fibers under the
modeling of fiber optic link showed good results for a few-mode regime of high-speed laser-based serial data transmission.
However on practice a different distributed core geometry parameter variation occurs in real optical fibers due to
techniques features of preform manufacturing and fiber drawing. Here results of fiber optic link modeling with proposed
multimode fibers 50/125 with low DMD under core diameter variation and refractive index profile deviation from the
optimal form, and estimation of their influence on a few-mode optical signal distortion are represented.

The article is devoted to research of the approach to pulse distortions definition arising under action of birefringence
effects in fiber. The analysis of existing methods of an such distortions estimation used on network is executed. Except
increase of a pulse duration under polarizing dispersion it is offered to estimate effects connected with nonlinear
birefringence and interaction polarizing dispersion with losses, dependent from polarization. Modeling the specified
factors is carried out. The set of factors effectively describing such distortions of a pulse is offered.

We analyze the most effective way to obtain microwave-photonic filter's coefficients, specifically implemented by electro-
optical modulators. These devices are attractive to obtain desired number and sign of coefficients which results in
high tunability and reconfigurability of filters. One have to decide which device will be the most appropriate in obtaining
desired frequency response of the filter. The results of numerical simulations are presented for phase modulator, singleport
mach-zehnder modulator and dual-port mach-zehnder modulator.

Problem of short-term operating point dc-drift of an asymmetric waveguide topology X-cut integrated optical Mach-
Zehnder interferometer has been considered. A magnitude of dc-drift was estimated with optical intensity change after
voltage switching. It was shown, that short-term dc-drift depends on initial operating point position. Two types of shortterm
dc-drift were detected and described.

A simple semi-empirical model for chromatic dispersion estimation of dispersion compensating photonic-crystal fibers
in a limited range of wavelengths is presented in this paper. The proposed approach is widely used in the field of
electromagnetic waves of the microwave range, for instance, for calculation of approximate estimates of the
effectiveness of electromagnetic shields and here in this paper we adopted it for the estimation of chromatic dispersion of
photonic-crystal fibers. It worth to note that this approach provides the possibility to evaluate approximate magnitude of
the chromatic dispersion of dispersion compensating photonic-crystal fibers without extensive numerical calculations,
but the main drawback of this method is that the validity of it is restricted only for the certain range of the wavelengths.

A method is suggested for design of refractive optical surface intended for generation of the prescribed irradiance
distribution. The method is based on the gradient optimization of the refractive surface represented as a bicubic spline in
spherical coordinates. An optical element for direct-type backlight system was designed. The element produces
uniformly illuminated hexagonal region with angular size of 143° at the distance of 15 mm from the Luxeon® Rebel
Cool-White LED. The RMS error of generated irradiance distribution from the constant value is 3-4% with an energy
efficiency greater than 81%. The simulation data shows that a large, uniformly illuminated region can be formed by
means of a system of the indicated elements, located at the nodes of a rhombic grid.

We present a distributed image approach to image data management in distributed storage and parallel processing
systems. This approach allows to avoid parallel processing bottlenecks and overlap concerned with image data
read/write. The distributed image is defined as a set of the overlap fragments. Their overlap size is determined by
the requirements of fault tolerance and dynamic load balancing. Within this concept, we propose a decentralized
method for dynamic load balancing of parallel computing and visualization solutions for large-size distributed
images.

The problems of RZ, CS-RZ and soliton generation and the problems of transmitters building for regional and
intercontinental fiber optic-based solutions are proposed in order to assess their applicability and implementation of
given formats and the soliton regime for the organization of access networks (1-10 Gb/s, ≤ 100 km). We have proposed
and demonstrated in recent years an unique technique to synthesize the two frequency radiation by manipulating the
amplitude and the phase of initial one frequency lightwave. The output frequencies are symmetrical relatively to
suppressed initial one and have equal amplitudes and alternative phases. It's applications are considered.
