Abstract
The development of the world ocean shelf requires the use of a variety of underwater communication equipment. The results of simulation of the shape of electrical pulses generated by 1-ns optical pulses from a photodetector are presented. These pulses propagate through a water layer containing only nanobubble clusters. Scattering from the volume behind the emitter was also taken into account. Attenuation was calculated using Bouguer's law. Cluster scattering efficiency factors were estimated using Mie theory for submicron particles with a refractive index lower than that of water. It was found that the broadening of a 1-ns pulse caused by scattering only by bubstons taking into account the volume behind the emitter does not exceed 0.1 ns at a distance of 20 m. It is shown that nanobubble clusters in transparent water limit the length of underwater optical wireless communication lines by attenuating the radiation. The results can be used in the development of devices for underwater wireless optical communication.
