gplugins.common.utils.get_effective_indices.get_effective_indices(core_material: float, nsubstrate: float, clad_materialding: float, thickness: float, wavelength: float, polarization: Literal['te', 'tm']) → list[float]

Returns the effective refractive indices for a 1D mode.

Parameters:

• epsilon_core – Relative permittivity of the film.

• epsilon_substrate – Relative permittivity of the substrate.

• epsilon_cladding – Relative permittivity of the cladding.

• thickness – Thickness of the film in um.

• wavelength – Wavelength in um.

• polarization – Either “te” or “tm”.
