Abstract

In the present paper we study the response to surrounding refractive index (SRI) changes of bent fused fiber tapers. The core-cladding mode interference response occurs at particular bending angles and the refractometric response exhibits different sensitivities. The sensitivities greater than 3000 nm/r.i.u. for SRI (surrounding refractive index) larger than 1.43 and as high as 6000 nm/r.i.u. are reached for SRI above 1.44.
