Graded-index fiber with FEEM

This example shows how to use the FEEM to calculate the characteristic modes of a graded-index fiber. A spatially varying refractive index profile is generated using the (n, k) material attribute tool. The field distributions and effective indices of the lower order modes are calculated and compared with analytical results. Więcej…

Step-index fiber (FEEM)

In this example we show how to use the FEEM to study a step-index fiber. Using the built-in analysis tools, we will calculate the field distributions and effective indices of some of the modes supported by the fiber. The simulation results are then compared with a semianalytical calculation done with Więcej…
