We present the complete (analytical, numerical and experimental) analysis of intermodal-vectorial four-wave mixings proccesses in birefringent fibers. We analyze phase-matching condition and overlap coefficients to indicate possible processes. Then, we demonstrate multiple four-wave mixing processes in LP01 and LP11 modes numerically and experimentally. Finally, we extend theoretical analysis to account higher-order modes, LP02 and LP21.

In this work, we present the results of numerical modelling of nonlinear pulse propagation in multimode optical fibers leading to discretized conical emission.
We investigate polarization conversion between two linearly polarized soli-tons in microstructured birefringent optical fibers.

Counting bacterial colonies is a fundamental task in microbiology. Currently, manual counting remains the gold standard. This is a timeconsuming and error-prone process, which requires a trained professional. To avoid these issues, the automated method can be applied for the task. The goal of our work was to design a model that counts and classifies bacterial colonies in Petri dishes using RGB images.
The field distribution of the same mode could be slightly different depending on wavelength and reflective index profile. To exhibit a dispersion characteristic for multimode fibers over a wide spectral range, a verification of refractive index value for a particular mode at a specific wavelength is needed.
There is an urgent need of clarifying the potential and areas of applicability of numerical models to facilitate the accurate design of future nonlinear and multimode fiber devices. Therefore we performed the simulations of conical emission using two well-known numerical tools, namely, the unidirectional pulse propagation equation and the multimode generalized nonlinear Schrodinger equation.
Our simulations show that all-normal dispersion supercontinuum generated in optimized microstructured fiber (with hexagonal and kagome geometry) covers whole transparency window of silica glass.
We extended a theoretical model of self-organized SHG to include an attenuation and investigated the influence of fiber loss on the self-organized SHG process.
