tidy3d.ModeAmpsData

class tidy3d.ModeAmpsData

Stores modal amplitdudes from a ModeMonitor.

Parameters

• values (Array) – Multi-dimensional array storing the raw, complex mode amplitude values.

• data_attrs (Mapping[str, str] = {'units': 'sqrt(W)', 'long_name': 'mode amplitudes'}) – Dictionary storing extra attributes associated with the monitor data.

• f (Array) – [units = Hz]. Array of frequency values to use as coordintes.

• mode_index (Array) – Array of mode index values to use as coordintes.

• direction (List[Literal['+', '-']] = ['+', '-']) – List of directions contained in the mode amplitude data.

Example

>>> f = np.linspace(2e14, 3e14, 1001)
>>> mode_index = np.arange(1, 3)
>>> values = (1+1j) * np.random.random((2, len(f), len(mode_index)))
>>> data = ModeAmpsData(values=values, direction=['+', '-'], mode_index=mode_index, f=f)

Fields

• data_attrs (Dict[str, str])

• direction (List[Literal['+', '-']])

• values (tidy3d.components.types.Array)

attribute data_attrs: Dict[str, str] = {'long_name': 'mode amplitudes', 'units': 'sqrt(W)'}

explanation of values values is a numpy array that stores the raw data associated with each MonitorData. It can be complex-valued or real valued, depending on whether data is in the frequency or time domain, respectively. Each axis in values corresponds to a specific dimension in the MonitorData, which are supplied as arguments to the MonitorData subclasses. The order of the dimensions is specified in the _dims attribute of each MonitorData subclass

Dictionary storing extra attributes associated with the monitor data.

attribute direction: List[Literal['+', '-']] = ['+', '-']

List of directions contained in the mode amplitude data.

attribute values: tidy3d.components.types.Array [Required]

Multi-dimensional array storing the raw, complex mode amplitude values.

Constraints

• title = NumpyArray

• description = Wrapper around numpy arrays that has a well defined json schema.
