Abstract
We have used Brillouin phase conjugation to demonstrate compensation of phase aberrations and depolarization induced by a multi-mode fiber, and we have achieved a high degree of fidelity. Although the relatively weak signal-beam power led to our selection of a PCM based on Brillouin enhanced four-wave mixing (BEFWM), with its associated complexities, simple SBS PCMs are capable of thresholds much less than those of the present device. For example, the use of longer capillaries (lengths of several meters) with smaller cross sections (100 /spl mu/m) has been shown to yield SBS threshold powers as low as /spl sim/ 100 W.Keywords
