WebAn optical phase conjugation device is associated to one of the amplifiers of the plurality of amplifiers, and is disposed in combination with an optical fiber length having the same … WebIt is distinguished from Time Reversal Signal Processing by the fact that phase conjugation uses a holographic or parametric pumping whereas time reversal records and re-emits the signal using transducers. [1] Holographic pumping makes the incident wave interact with a pump wave of the same frequency and records its amplitude-phase distribution.

WebBy using the property of phase conjugation, we demonstrate that the inverse of van Cittert– Zernike theorem holds for electromagnetic (EM) ﬁelds propagating in free space. This essentially implies that spatially incoherent partially polarized ﬁeld distributions can be generated from spatially coherent partially polarized optical ﬁelds. WebWe deploy kernel-based time-series prediction to suppress the phase noise induced by small deviations from ideal pump counter-phasing in a dual-pump optical phase conjugation system. We show experimentally 1.5-dB SNR improvement for 16-QAM signals at 4° pump-phase mismatch.
