Abstract
In this study, the characteristics of optical radiation transmitted through the elements of a fiber-optic acousto-optic (AO) switch were investigated. The transmission efficiency of the optical signal and the insertion losses were determined. We proposed a mathematical model of an AO switch for fiber-optic communication lines; the model describes the propagation of an optical signal as the transmission of Gaussian radiation between the input and output fibers. The designed mathematical model enables the determination of the amplitudes, intensities, and power ratios of the signals in the input and output optical fibers, as well as the propagation pattern of the optical radiation and the radiation attenuation by the optical elements. Moreover, it allows the estimation of the optical signal transmission efficiency and the insertion losses.
