get_nearest_neighbor_crosstalk

awg_designer.all.get_nearest_neighbor_crosstalk(smatrix, input_pm, output_pms, channel_wavelengths)

Get the nearest neighbor cross-talk for each output port.

The cross-talk is calculated by looking for the max transmission inside each filter band due to its nearest neighbors.

Parameters:

smatrix:

SMatrix object as a result of a circuit simulation.

input_pm: string

The input port/mode. For single-mode, you only need to specify the port name.

output_pms: List[str]

List of output “port:mode” names for which to get the nearest neighbor crosstalk.

channel_wavelengths: List[float]

List of the center wavelengths of each channel. Used to limit the wavelength range to 1 FSR and define the bands.
