LightInteraction#

class LightInteraction(name, side, sign, readout=False, angle=0.0, parent=None, children=None)[source]#

Bases: anytree.node.nodemixin.NodeMixin

Represents (dipole) interaction between the system and a light beam.

Parameters

  • name (str) – Identifier for the light beam.

  • side (rotsim2d.pathways.Side) – Ket or bra excitation.

  • sign (rotsim2d.pathways.KSign) – Wavevector sign of created polarization contribution.

  • readout (bool) – Readout or actual light interaction.

  • angle (Union[float, Tuple[float, float]]) – Single float for linear polarization and pair of numbers for elliptical.
