Abstract
The backgrounds of the modern approaches in fiber telecommunications and laser sensing based on the quantum mechanics and quantum optics are presented. Also discussed the field quantization in free space and in the fibers and cavities, the coupling between relaxation and noise sources, laser linewidth calculation and laser quantum equations. Limitations of ultra-short pulse fiber laser radiation due to quantum fluctuations are presented. The Schmidt decomposition and Schmidt information are discussed in the context of the Einshtein Podolsky Rozen states and entanglement are discussed, together with the conception of quantum illumination and quantum radars. Entangling parameter is discussed for different schemes of generation of entangled states (parametric generation and two-soliton pulse fission in dispersion oscillating fiber). Schemes of quantization of soliton pulses in optical fiber is presented and squeezing and entanglement are discussed. Some experiments of the measurement of quantum fluctuations of the soliton pulses and its correlations and demonstration of the soliton fission in the dispersion oscillating fiber are presented. The theoretical and numerical approached for the calculations of quantum fluctuations during soliton pulse propagation in the fibers are presented. Some perspectives of the use of the entangled pulses for sensing and fundamental physics experiments are discussed, with some problems in this field.
