optic.models.devices.edfa

edfa(Ei, param=None)

Implement simple EDFA model.

Parameters:

• Ei (np.array) – Input signal field.

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

  Parameters of the EDFA model.

  • param.G : amplifier gain [dB][default: 20 dB]

  • param.NF : EDFA noise figure [dB][default: 4.5 dB]

  • param.Fc : central optical frequency [Hz][default: 193.1 THz]

  • param.Fs : sampling frequency in [samples/s]

  • param.seed : random seed for noise generation [default: None]

Returns:

Eo – Amplified noisy optical signal.

Return type:

np.array
