WebNov 15, 2001 · In semiconductor lasers most studies have been carried out with conventional or phase conjugate optical feedback i.e. phenomena which originate from the coupling between the optical intensity, the carriers, and the phase difference between the laser output and the delayed field [4]. It is interesting to examine the situation where the … 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.
