Simulation of a Fiber-optical Communication SystemScheffel, Patricia Kay 01 January 1977 (has links) (PDF)
The feasibility of analyzing an optical communication system using standard electronic circuit analysis programs such as SCEPTRE and ASTAP is demonstrated in this thesis. The transmitter (laser and modulator) and receiver (detector and amplifier) are modelled using equivalent circuits for the various components. The transmission medium (optical fiber) is modelled using an impulse response function. Two fibers are investigated--a step-index fiber and a square-law (parabolic index) fiber.

Statistical Fading of a Plane Optical Wave in Atmospheric TurbulenceO'Hara, John F. 01 January 1980 (has links) (PDF)
A formula for the average fade time of the intensity of a plane optical wave traveling through atmospheric turbulence is developed. The model employed involves isotropic, homogeneous statistics using a lognormal distribution for the channel. The analysis is based on the fact that the logarithm of the irradiance is normally distributed and uses the work of S. O. Rice who developed such an expression for a zero mean, Gaussian process. The analysis employs the covariance function and the Taylor frozen turbulence hypothesis which results in an expression for the autocorrelation function.

Fade Time Statistics of Laser Light Propagating Through Turbulent AtmosphereBelkerdid, Madjid A. 01 January 1980 (has links) (PDF)
The average fade time of the fluctuations in the intensity of laser light propagation in the atmosphere is analyzed. Experimental results show that the average fade time for a propagation distance of 208 meters, in the weak turbulence regime, is well described by formulas developed from a Log-Normal distribution. A circuit that calculates real time statistics of fade time is designed, then validated using a sine wave input whose fade time statistics are predetermined. The experimental signal is then tested for stationarity, and the average fade time is measured. A curve fitting is then performed for the experimental data and compared theoretical results.
