Enhanced structural sensitivity of hybrid-mode acoustic phonons in axially-varying photonic crystal fiber
"We report the observation of anti-crossings between hybridmode acoustic phonons in an axially-varying photonic crystal fiber. Our experimental results are analyzed using an electrostriction theory which reveals strong coupling between longitudina [...]
