Combining interferometric sensors for dual parameter fiber optic chemical sensing

Combining interferometric sensors for dual parameter fiber optic chemical sensing

Long and short path length differences interferometric sensing modalities have been combined based on immobilizing hydrogel on thin-core optical fiber end face. Dual parameter sensing of hydrogel swelling and refractive index was demonstrated.
