Brillouin backscattering in a high-index doped silica chip waveguide
Résumé
We investigate, both experimentally and theoretically, Brillouin backscattering in a 50-cm long high-index (n=1.7)
doped-silica glass photonic chip waveguide. The Brillouin spectrum features a broad (350 MHz) acoustic resonance at
16 GHz, in good agreement with theory and numerical simulations. Brillouin gain was estimated to be around 0.09 1/m/W.
