3.2.3.12. lekkersim.PolRot

class lekkersim.PolRot(angle: float = None, angle_name: str = 'angle')

Model of a 2 modes polarization rotator

__init__(angle: float = None, angle_name: str = 'angle') → None

Initialize the model

If angle is provided the rotation is fixed to that value. If not, the rotation is assumed

variable and the angle will be fetched form the parameter dictionary.

Parameters:

  • angle (float) – fixed value of the rotation angle (in pi units). Default is None

  • angle_name (str) – name of the angle parameter

Methods

S2PD([func])

Function for returning the Scattering Matrix as a PD Dataframe

__init__([angle, angle_name])

Initialize the model

create_S()

Function for returning the scattering matrix of the model

expand_mode(mode_list)

This function expands the model by adding additional modes.
