In this paper we investigated a problem of intermode dispersion within a group of optical vortices with an azimuthal number greater than or equal to 1 in circular optical fibers. It was established that, while there is no dispersion between optical v

In this paper, we theoretically study the transmission of optical vortices (OVs) through a uniform N-turn coil of a multimode fiber. We suggest a scalar-approximation treatment based on coupled mode equations in slow amplitudes and study transformati

We show that a multihelical optical fiber at certain parameters can be used for the high efficient transformation of EH- and HE-modes to linearly polarized optical vortices with topological charge +|l| and –|l|, respectively. We establish that the

We have studied the effect of strong coupling on the propagation of optical vortices (OVs) and evolution of their orbital angular momentum (OAM) in parallel multimode optical fibers. Based on the perturbation theory that goes beyond the limits of wea

In this paper, we studied an effect of strong evanescent coupling on the structure of normal modes in a system of parallel ideal multimode optical fibers. Using the formalism of the degenerate perturbation theory and a scalar waveguide equation for t

In this paper, we have theoretically studied an effective amplification of optical activity by a fiber loop resonator. We propose a scheme in which an optically active element is placed in the loop segment of the resonator. Assuming that the coupling

In this paper we study the propagation of optical vortices (OVs) through the loop resonator (LR) on a multimode fiber. Within the framework of a fully vectorial treatment that allows for the spin-orbit interaction (SOI) we demonstrate the existence i

In this paper we theoretically study the propagation of optical vortices (OVs) through a loop resonator (LR) on a multimode optical fiber. We demonstrate the presence in LRs of a resonance, which is in the inversion of the topological charge (TC) of
