simulate_crossing

si_fab.components.crossing.simulation.simulate_lumerical.simulate_crossing(layout, project_folder, mesh_accuracy=1, wavelengths=(1.5, 1.6, 100), inspect=False)

Simulates a crossing with Lumerical and returns an smatrix. The crossing is assumed to be 4-way symmetric.

Parameters:

layouti3.LayoutView

Layout of a crossing. The crossing is assumed to have ports “in1”, “out1”, “in2”, “out2”

project_folderstr

Folder in which the simulation is performede

mesh_accuracyint, optional

Accuracy of the mesh, 1 is coarse 5 is fine

wavelengthstuple, optional

Tuple of the simulation range (start_wav, end_wav, n_samples)

inspectboolean, optional

Inspect the simulation project before running

Returns:

smatrix
