Fiber Modes

This BeamLab demo calculates the field distributions and effective refractive indices of the eigenmodes of a step-index fiber with a circular core.

BeamLab demo script: fiber_modes.m

The following figures show the three field components of the first 4 low-order modes as field contour lines. The black lines indicate the core-cladding boundary.

Mode 1

Mode 2

Mode 3

Mode 4
