gaussian_radial_irradiance
- ofiber.cylinder_step.gaussian_radial_irradiance(V, r_over_a)[source]
Calculate the normalized irradiance in a step-index fiber.
The normalization is done assuming the Gaussian envelope approximation for the LP_01 mode. The result is normalized such that np.trapz(Gaussian(r_over_a)*r_over_a, r_over_a) = 1/2
- Parameters:
V – V-parameter for fiber [-]
r_over_a – (radial position)/(core radius) [-]
- Returns:
normalized irradiance at points r_over_a [-]
