tidy3d.components.data.dataset.ModeSolverDataset

class ModeSolverDataset

Bases: ElectromagneticFieldDataset

Dataset storing scalar components of E and H fields as a function of freq. and mode_index.

Parameters:

• Ex (Optional[ScalarModeFieldDataArray] = None) – Spatial distribution of the x-component of the electric field of the mode.

• Ey (Optional[ScalarModeFieldDataArray] = None) – Spatial distribution of the y-component of the electric field of the mode.

• Ez (Optional[ScalarModeFieldDataArray] = None) – Spatial distribution of the z-component of the electric field of the mode.

• Hx (Optional[ScalarModeFieldDataArray] = None) – Spatial distribution of the x-component of the magnetic field of the mode.

• Hy (Optional[ScalarModeFieldDataArray] = None) – Spatial distribution of the y-component of the magnetic field of the mode.

• Hz (Optional[ScalarModeFieldDataArray] = None) – Spatial distribution of the z-component of the magnetic field of the mode.

• n_complex (ModeIndexDataArray) – Complex-valued effective propagation constants associated with the mode.

• n_group_raw (Optional[GroupIndexDataArray] = None) – Index associated with group velocity of the mode.

• dispersion_raw (Optional[ModeDispersionDataArray] = None) – [units = ps/(nm km)]. Dispersion parameter for the mode.

Example

>>> from tidy3d import ModeSpec
>>> x = [-1,1]
>>> y = [0]
>>> z = [-3,-1,1,3]
>>> f = [2e14, 3e14]
>>> mode_index = np.arange(5)
>>> field_coords = dict(x=x, y=y, z=z, f=f, mode_index=mode_index)
>>> field = ScalarModeFieldDataArray((1+1j)*np.random.random((2,1,4,2,5)), coords=field_coords)
>>> index_coords = dict(f=f, mode_index=mode_index)
>>> index_data = ModeIndexDataArray((1+1j) * np.random.random((2,5)), coords=index_coords)
>>> data = ModeSolverDataset(
...     Ex=field,
...     Ey=field,
...     Ez=field,
...     Hx=field,
...     Hy=field,
...     Hz=field,
...     n_complex=index_data
