mzm(Ei, u, param=None)

Optical Mach-Zhender Modulator (MZM).

Parameters:

• Ei (scalar or np.array) – Optical field at the input of the MZM.

• u (np.array) – Electrical driving signal.

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

  Parameters of the MZM model.

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

  • param.Vb : MZM’s bias voltage [V][default: -1 V]

  • param.ER : MZM extinction ratio [dB][default: 60 dB]

Returns:

Modulated optical field at the output of the MZM.

Return type:

np.array
