“…The free-space optical communication (FSO) asymmetric link based on a corner-cube retroreflector (CCR) has the advantage of low cost and low power in comparison with symmetric links [1][2][3]. There are two dissimilar optical terminals in an asymmetric FSO link.…”

In order to obtain the change in the return laser-pulse peak-power instability with the distance between two communication terminals in a free-space optical communication (FSO) asymmetric link, which uses a corner-cube retroreflector (CCR) and a high peak-power pulse laser, we present the peak power instability of laser pulses retroreflected by the CCR at different distances. The CCR bottom surface was a circle with a diameter of 1 in., and three mirrors of the CCR were coated with silver. The weather was cloudy with winds of Category 4. The distances from the transmitter to the CCR were 120, 1,550, 3,900, and 5,240 m. The laser emitted 100 laser pulses with a peak power of 5 MW at each distance. The results of the experiments show that the increase in both absolute and relative peakpower instabilities with the distance is approximately linear. The absolute peak-power instability is more than 58.7 mV and the relative peak-power instability is more than 11.8% if the distance increases 1 km.

Scintillation measurements of broadband 980-nm laser light in clear air turbulence

et al. 2004

Intensity scintillation variances and intensity probability density functions (PDF) were experimentally measured for broad-band (2nm), 980 nm laser light reflected by two corner-cube retro-reflectors as a function of retro-reflector lateral spacing over a short (75 m) atmospheric optical path. The PDFs transitioned from broad double peaked "beta -shaped" densities to log-normal ones as the retro-reflector spacing was increased to exceed the optical field lateral coherence length. Specific spacing for a given average atmospheric refractive index structure constant C n 2 eliminated coherent interference between light beams returned by each retro-reflector.

“…Propagation losses in folded-path free-space optical communication links that employ modulating retro-reflectors increase as the fourth power of one-way link distance as opposed to distance squared for one-way point-to-point links [1], [2]. It is therefore necessary to maximize receiver sensitivity to make these types of folded-path links effective.…”

Receiver performance is calculated for two types of free-space atmospheric optical communications systems -a direct detection system using a p-i-n photodiode preceded by an optical amplifier, and an ideal coherent receiver operated in its shot-noise limited regime without an optical pre-amplifier. The signal format for both is amplitude shift keying (onoff modulation) with an assumed rectangular light pulse of duration T seconds. The more accurate Beckman probability density function (pdf) is used to describe the intensity fading rather than the more commonly used log-normal pdf which overestimates receiver performance. A coherent receiver using asynchronous detection is shown to outperform the direct detection system with an optical pre-amplifier gain of 30 dB by anywhere from 7 to about 10 dB depending on Rytov variance intensity fading levels. In addition, the effect of inner scale turbulence parameter, l 0 , on system bit error rate is demonstrated.
