TL;DR

This paper explores phase dislocations and vortex formation in the electric fields of hollow core waveguides, revealing limitations of existing models and emphasizing the importance of phase jumps for accurate phase behavior description.

Contribution

It introduces a detailed analysis of phase dislocations in hollow core waveguides, highlighting the need to consider phase jumps beyond the ARROW model for accurate understanding.

Findings

Phase dislocations lead to vortex formation in electric fields.

The ARROW model is insufficient to fully describe phase behavior.

Phase jumps of pi are crucial for accurate phase analysis.

Abstract

This paper discusses the basic concepts of phase dislocations and vortex formation in the electric fields of fundamental air core mode of hollow core waveguides with specific types of rotational symmetry of the core cladding boundary. Analysis of the behavior of the electric field phase in the transmission bands shows that the mechanism of light localization in the hollow core waveguides with discrete rotational symmetry of the core cladding boundary cannot be completely described by the ARROW model. For an accurate description of the phase behavior, it is necessary to account for phase jumps of the magnitude of pi when passing through the phase dislocations.
