Experimental Works on Free-Space Optical Communications with Aperture Averaging and Receive Diversity in a Controlled Laboratory Environment

چکیده
In this paper, fading mitigation by aperture averaging and receive diversity in Free-Space Optical (FSO) systems is experimentally investigated in a controlled atmospheric chamber. Some previous theoretical studies and the configuration of the experiment setup are described. Then, we introduce the turbulence measurement and performance evaluation for the FSO system briefly. The Q-factor is calculated from the experimental data to validate the performance improvement obtained by aperture averaging and receive diversity. In addition, we calculate the correlation coefficients corresponding to a receive diversity FSO system and the probability density function (PDF) of each channel fading.

متن کاملExperimental verification of an adaptive optical multi-aperture receive antenna for laser space communications
The feasibility of phased telescope arrays for coherent optical space communications is demonstrated by a proof-ofconcept laboratory experiment. The incident optical power is collected by four subtelescopes and coherently combined into a single monomode output fiber. The implemented optical receive array antenna is self-phasing, i.e. the optical subfield pistons are automatically adapted with r...
متن کاملImproving the directivity of the plasmonic sectoral horn nanoantenna using lens in its aperture
Horn antennas can result in good impedance matching between the waveguide and free space due to the gradual increase in the aperture size. In this paper, a novel plasmonic sectoral horn nanoantenna based on using lens in the aperture is proposed. It is investigated that in addition to improvement of the directivity, the reflection coefficient is also reduced using the proper lens structure. The...

The concept of an adaptive receive telescope array (RTA) for coherent optical space communications is presented. The RTA consists of N=2, e.g. 16, subtelescopes, N polarization-maintaining single-mode fibers, N optical phase actuators, a binary tree of N-1 symmetrical polarization-maintaining directional couplers, N-1 optical power sensors, and a digital control unit. The output interface, a po...
