“…For optical wave propagation, the classic Kolmogorov model has been widely used in theoretical researches due to its simple mathematical form [3][4][5]. Over the years, the Kolmogorov model is extended and several non-Kolmogorov turbulence models have been also proposed [6][7][8][9][10][11][12][13]. Toselli et al [6] is one of them, and they analyze the angle of arrival fluctuations by using the generalized exponent factor α instead of the standard exponent value 11/3.…”

For the free-space optical (FSO) communication system, the spatial coherence of a laser beam is influenced obviously as it propagates through the atmosphere. This loss of spatial coherence limits the degree to which the laser beam is collimated or focused, resulting in a significant decrease in the power level of optical communication and radar systems. In this work, the analytic expressions of wave structure function for plane and spherical wave propagation through anisotropic non-Kolmogorov turbulence in a horizontal path are derived. Moreover, the new expressions for spatial coherence radius are obtained considering different scales of atmospheric turbulence. Using the newly obtained expressions for the spatial coherent radius, the effects of the inner scales and the outer scales of the turbulence, the power law exponent, and the anisotropic factor are analyzed. The analytical simulation results show that the wave structure functions are greatly influenced by the power law exponent α , the anisotropic factor ζ , the turbulence strength σ ~ R 2 , and the turbulence scales. Moreover, the spatial coherence radiuses are also significantly affected by the anisotropic factor ζ and the turbulence strength σ ~ R 2 , while they are gently influenced by the power law exponent α and the inner scales of the optical waves.

“…Free space optical (FSO) communication has many advantages over microwave communications, such as light weight, high speed data capacity and immunity to interference. [1][2][3][4][5] FSO communication has important applications for intersatellite communications with a few successful in-orbit demonstrations in recent years. [6][7][8][9] However, compared to the ground terminals, the transmitters of intersatellite optical links (IOLs) are limited by the narrow beam width and low power.…”

A stable and accurate pointing, acquisition system is an important part of initially building intersatellite optical communication links. Satellite platform vibration can cause the system instability and reduce the system precision in building and maintenance of a satellite optical communication system. In this paper, vibration influence is consciously discussed by acquisition time for intersatellite optical communications. Analytical expression of acquisition possibility is derived, taking the scan parameters and platform vibration into account, and vibration influence on the multi-scan acquisition time is also presented. The theoretical result calculated by the proposed analytical expression is approximate to the result by the Monte Carlo simulation.

“…The model was studied in the recent years. [10][11][12][13][14] An elliptical beam model considering beam wandering, broadening and deformation has been established for quantum light through the atmospheric channel, [15] then others factors, such as arrival time fluctuations and angle-of-arrival fluctuations, were also considered in this model. [16][17][18][19] However, in the QKD system, the quantum states in atmospheric channels are sensitive to fluctuation of temperature.…”

Compared with the fiber channel, the atmospheric channel offers the possibility of a broader geographical coverage and more flexible transmission for continuous-variable quantum key distribution (CVQKD). However, the fluctuation of atmospheric conditions will lead to the loss of performance in atmospheric quantum communication. In this paper, we study how temperature affects atmospheric CVQKD. We mainly consider the temperature effects on the transmittance and interruption probability. From the numerical simulation analysis, it can be shown that the performance of atmospheric CVQKD is improved as temperature increases, with the other factors fixed. Moreover, the results in this work can be used to evaluate the feasibility of the experimental implementation of the atmospheric CVQKD protocols.
