SCEE Integration¶
These are the wrappers that provide an interface to enable use of all of the SCEE models in simphony photonic toolbox and Lumerical Interconnect. This gives the user multiple options (Interconnect or Simphony) to cascade devices into complex structures.
Interconnect Exporter¶
-
SiPANN.scee_int.
export_interconnect
(sparams, wavelength, filename, clear=True)¶ Exports scattering parameters to a file readable by interconnect
Parameters: - sparams (ndarray) – Numpy array of size (N, d, d) where N is the number of frequency points and d the number of ports
- wavelength (ndarray) – Numpy array of wavelengths (in nm, like the rest of SCEE) of size (N)
- filename (string) – Location to save file
- clear (bool, optional) – If True, empties the file first. Defaults to True.
Simphony Wrapper¶
-
class
SiPANN.scee_int.
SimphonyWrapper
(model, sigmas={})¶ Class that wraps SCEE models for use in simphony.
Model passed into class CANNOT have varying geometries, as a device such as this can’t be cascaded properly.
Parameters: - model (DC) – Chosen compact model from
SiPANN.scee
module. Can be any model that inherits from the DC abstract class - sigmas (dict, optional) – Dictionary mapping parameters to sigma values for use in monte_carlo simulations. Note sigmas should be in values of nm. Defaults to an empty dictionary.
-
pins
= ('n1', 'n2', 'n3', 'n4')¶ The default pin names of the device
-
freq_range
= (182800279268292.0, 205337300000000.0)¶ The valid frequency range for this model.
-
s_parameters
(freq)¶ Get the s-parameters of SCEE Model.
Parameters: freq (np.ndarray) – A frequency array to calculate s-parameters over (in Hz). Returns: s – Returns the calculated s-parameter matrix. Return type: np.ndarray
-
monte_carlo_s_parameters
(freq)¶ Get the s-parameters of SCEE Model with slightly changed parameters.
Parameters: freq (np.ndarray) – A frequency array to calculate s-parameters over (in Hz). Returns: s – Returns the calculated s-parameter matrix. Return type: np.ndarray
-
regenerate_monte_carlo_parameters
()¶ Varies parameters based on passed in sigma dictionary.
Iterates through sigma dictionary to change each of those parameters, with the mean being the original values found in model.
- model (DC) – Chosen compact model from
