“…If the multimode fiber (plastic or glass) is used as a final fiber, the optical intensity distribution in the transmitted beam will generate a so-called "top-hat" beam [2], which is more resistant to the negative effects of atmospheric turbulence in comparison with the standard Gaussian beam. The "top-hat" distribution of optical intensity in a plane perpendicular to the axis of the beam is shown in Fig.…”

The paper deals with terrestrial optical wireless links operating with coherent laser beams. The contribution discusses the full photonic transceiver concept (transmitter and receiver). Two main types of optical wireless links are mentioned: test link and data link. The purely photonic concept of the links with its advantages over the conventional concept is presented and discussed. The modeling of the full photonic receiver using matrix optics is shown.

This study is focused on analysing the optimal distribution of optical intensity within a radiated laser beam at a transmitter plane which is propagated through free space as well as through a turbulent atmosphere. To analyse the propagation of an optical wave through atmospheric turbulence, the simulation, based on the split-step beam propagation method, was utilised. The aim of this study is to determine the optimal parameters for a flattened Gaussian beam at the transmitter plane. As a result, the scintillation index should be reduced. There are a number of theoretical studies aimed at propagating the flattened beam despite the lack of experimental work in this area. Therefore the techniques for generating the flattened Gaussian beam will also be mentioned.
