Phase-Matching Condition between Acoustic and Optical Waves in Doped Fibers

View publication


A study was performed on the phase-matching condition between acoustic and optical waves in doped fibers. A technique was also proposed for achieving phase-matching in Brillouin scattering in a dielectric fiber doped by three-level λ-type ions. It was found that the technique led to a significant increase of efficiency of ponderomotive nonlinear interaction between electromagnetic waves.
