Rayleigh scattering, as a representative of distributed optical feedback, has a better linewidth compression effect in the field of narrow linewidth lasers, which has been experimentally proved. However, up to now, the linewidth compression mechanism especially for the frequency evolution mechanism of laser in Rayleigh scattering medium structure has not been systematically investigated.
The research group of Prof. Tao Zhu from Chongqing University demonstrates the dynamic characteristics of the spectrum evolution (SpE) of Rayleigh scattering in a one-dimensional waveguide based on the quantum theory and establish a corresponding SpE-model. By means of simulation, the evolution law which represents the dynamic process of the spectrum linewidth at a state of continuous scattering is revealed.
