Abstract

This paper deals with multi-channel wireless links with a higher range designated for free-space optical (FSO) communications in an atmospheric media. Propagation of the optical beam in the atmosphere is analyzed and a novel approach of the photonic transmitter was proposed and analyzed. The simulation is carried out for the dual optical link. The link budget was analyzed for both wavelengths in the atmospheric windows - 850 nm and 1550 nm. Optical intensity distribution of the transmitted beam was also examined. At the end, measurements and simulations were carried out to verify the accuracy of the simulation of individual components used in the wireless link.
