Polarization of Brillouin scattered light in silica nanofibers

Résumé

We investigate both theoretically and experimentally the polarization properties of Brillouin light scattering in silica optical nanofibers. Our results show that while all hybrid acoustic waves scatter light without altering the state of polarization, one of the surface acoustic wave generates a depolarized Stokes light. Because of the slight ellipticity of the nanofiber, the surface wave is actually split into two torso-radial modes which give rise to polarization scrambling of the backward Brillouin Stokes signal. Our model also predicts that the polarization of the scattered light can be restored for one specific pump polarization.
