This article illustrates the method and system of polarization mapping of two-dimensional length distributions of individual Mueller-matrix images of biological layers, which are azimuthally independent with respect to the direction of their laser irradiation. The intellectual analysis of the named distributions involves the determination of their informative features as statistical and correlation moments of the 1st to 4th order, according to which their further classification is implemented on the basis of binomial logistic regression. The improved system with expanded functionality allowed to obtain an assessment of the reliability of the diagnosis of the pathology of the cervix at the level of 90% to 97.8%.
We present rate equation model of a modified vertical surface-emitting laser with two optical-coupled active cavities (СС-VSCEL) and external optical channel. The model allows to determine all the relevant parameters – carrier densities, gains, and output powers – starting from two input parameters: the injection currents in each cavity taking into account the additional external photonic injection. The system of rate equations is solved for different operating regimes of the modified laser device. The results provided by the model shown that operating characteristics of CC-VCSEL greatly depend on the number of photons of the external injection.
