optic.models.modelsGPU.edfa

edfa(Ei, param)[source]

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 in dB [default: 20 dB].

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

    • param.Fc : central optical frequency [default: 193.1e12 Hz].

    • param.Fs : sampling frequency in samples/second [default: None].

    • param.prec : numerical precision [default: cp.complex128].

    • param.seed : seed for the random number generator [default: None].

Returns:

Eo – Amplified noisy optical signal.

Return type:

np.array
