iqm(Ai, u, param=None)

Optical In-Phase/Quadrature Modulator (IQM).

Parameters:

• Ai (scalar or np.array) – Amplitude of the optical field at the input of the IQM.

• u (complex-valued np.array) – Modulator’s driving signal (complex-valued baseband).

• param (optic.utils.parameters object, optional) –

  Parameters of the MZM models.

  • param.Vpi: MZM’s Vpi voltage [V][default: 2 V]

  • param.VbI: I-MZM’s bias voltage [V][default: -2 V]

  • param.VbQ: Q-MZM’s bias voltage [V][default: -2 V]

  • param.Vphi: PM bias voltage [V][default: 1 V]

Returns:

Ao – Modulated optical field at the output of the IQM.

Return type:

complex-valued np.array
