LP_radial_irradiance

ofiber.LP_radial_irradiance(V, b, ell, r_over_a)[source]

Calculate the normalized irradiance in a step-index fiber.

The normalization is done such that integral_over_space/(area of core) = 1 or 2*np.trapz(LP(r_over_a)*r_over_a, r_over_a) =1

Parameters:

  • V – V-parameter for fiber [-]

  • b – normalized propagation constant [-]

  • ell – desired fiber mode [-]

  • r_over_a – (radial position)/(core radius) [-]

Returns:

normalized irradiance at points r_over_a [-]
