3x3 Line - Geometry Visualization

This script demonstrates how to create and visualize a 3x3 line geometry using the FiberFusing library.

from FiberFusing import Geometry, BackGround
from FiberFusing.fiber.catalogue import load_fiber
from FiberFusing.configuration.line import FusedProfile_03x03
from PyOptik import MaterialBank

Define the operational parameters

wavelength = 1.55e-6  # Wavelength in meters (1.55 micrometers)

Set up the background medium (air)

air_background = BackGround(index=1.0)

Create the cladding structure based on the fused fiber profile

cladding = FusedProfile_03x03(
    fiber_radius=62.5e-6,  # Radius of the fibers in the cladding (in meters)
    fusion_degree=0.3,  # Degree of fusion in the structure
    index=MaterialBank.fused_silica.compute_refractive_index(wavelength)  # Refractive index of silica at the specified wavelength
)

Load fibers (e.g., SMF-28) positioned at the cores of the cladding structure

fibers = [
    load_fiber('SMF28', wavelength=wavelength, position=core_position)
    for core_position in cladding.cores
]

Set up the geometry with the defined background, cladding structure, and resolution

geometry = Geometry(
    background=air_background,
    additional_structure_list=[cladding],
    x_bounds='centering',
    y_bounds='centering',
    resolution=250
)

Add the fibers to the geometry

geometry.add_fiber(*fibers)

Plot the resulting geometry

geometry.plot()
