Abstract

The use of optical vortices in fiber-optic communication lines is a promising direction, particularly for multiplexer creation. To generate an optical vortex and input/output it into/from the fiber, we utilized a biaxial crystal positioned between two parallel polarizers (a "sandwich" configuration). In our experiment, we employed a single-mode fiber and a He-Ne laser with a wavelength of 633 nm. For optical fiber communication, a similar approach involves using a multimode fiber with a core diameter of 20 μm, which allows the propagation of first and second-order vortices at a wavelength of 1550 nm. Based on the research results, the following conclusions can be drawn: a single singularity propagates better in the fiber than two simultaneously. This indicates that for a single singularity, the input beam apertures are better matched, whereas for two singularities, the input aperture is insufficient.
