FF_irradiance_x
- ofiber.FF_irradiance_x(r, theta, phi, ell, lambda0, a, V, b)[source]
Normalized far-field irradiance polarized in the x-direction.
This calculation is based eqn 10.12 for the far-field from Chen, Foundations for Guided-Wave Optics, Wiley-Interscience, 2007.
The magnitude of the field is squared and normalized by the square of the electric field magnitude.
- Parameters:
r – radial distance from the fiber axis (microns).
theta – polar angle in radians.
phi – azimuthal angle in radians.
ell – azimuthal mode number.
lambda0 – wavelength of light in the medium (microns).
a – Radius of the fiber core (microns).
V – normalized frequency parameter of the fiber.
b – normalized propagation constant.
- Returns:
The irradiance pattern as a function of r, theta, and phi.
