SUMMARY

The discussion centers on visualizing the electric field of optical fibers, specifically comparing it to dielectric slab waveguides. Participants highlight that while images of electric fields for slab waveguides are readily available, equivalent visualizations for optical fibers are scarce. Emily references a resource on LP modes, indicating that field expressions can be derived but not easily visualized for optical fibers. The need for clearer representations of these fields in optical fibers is emphasized.

PREREQUISITES
  • Understanding of dielectric slab waveguides
  • Familiarity with optical fiber modes
  • Knowledge of electromagnetic field theory
  • Basic skills in using visualization tools for electromagnetic fields
NEXT STEPS
  • Research methods for visualizing electric fields in optical fibers
  • Explore the mathematical derivation of LP modes in optical fibers
  • Learn about software tools for electromagnetic field visualization
  • Investigate the differences between slab waveguides and optical fibers in terms of field distribution
USEFUL FOR

Optical engineers, researchers in photonics, and students studying waveguide theory who seek to understand and visualize electric fields in optical fibers.

Hello!
For dielectric slab waveguides, starting from the field expressions, it is possible to draw the Electric field corresponding to a specific mode, showing its (possible) zeros inside the core and its exponential decay in the cladding:

A Google search can provide plenty of images like this one.
What about optical fibers instead? Is it possible to obtain an equivalent image, which corresponds to the obtained field expressions?
I couldn't find them.
