plot_LP_modes

ofiber.plot_LP_modes(V, ell)

Produce a plot show possible eigenvalue solutions for step index fiber.

The solutions correspond to places where the curves cross one another. No crossing means that there is no guided mode for that mode value.

Parameters:

• V – V-parameter for optical fiber [-]

• ell – primary fiber mode (integer) [-]

Returns:
