coherentReceiver(Es, Elo, paramFE=None, paramPD=None)

Single polarization coherent optical front-end.

Parameters:

• Es (np.array) – Input signal optical field.

• Elo (np.array) – Input LO optical field.

• paramFE (parameter object (struct), optional) –

  Parameters of the optical frontend:

  • paramFE.Fs : simulation sampling frequency [samples/s].

  • paramFE.phaseImb: phase imbalance of the I/Q [rad].

  • paramFE.ampImb: amplitude imbalance of the I/Q [dB].

  • paramFE.timeSkew: delay of the I of the I/Q [s].

• paramPD (parameter object (struct), optional) – Parameters of the photodiodes

Returns:

s – Downconverted signal after balanced detection.

Return type:

np.array
