WebJan 24, 2024 · Optical phase congugation is an effective method for non-linearity and dispersion management in optical fiber (Le et al. 2015; Hu et al. 2016; Watanabe et al. 1996 ). Figure 1 shows two basic methods of phase conjugation in optical fiber set-up. 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.
