Numerical Study of Phase Conjugation in Stimulated Brillouin Scattering from an Optical Waveguide.

摘要

Phase conjugation in stimulated Brillouin scattering (SBS) from an optical waveguide is studied numerically, using a Cartesian two dimensional propagation code (BOUNCE) that includes pump depletion. The simulations show that light scattered back through a phase aberrator produces a far field profile closely matching that of the incident beam; however, the near field intensity exhibits large and rapid spatial inhomogeneities across the entire aberrator, even for conjugation fidelities H as high as 98%.
