In this work, we report the exptl. investigation of the sensitivity characteristics to the surrounding refractive index (SRI) in thinned long period gratings for a wide range of fiber diams. and different low orders cladding modes. Wet chem. etching combined with microscopic anal. allow us to identify the exptl. dependence of the SRI sensitivity on the cladding radius.

Abstract
In this work, we report the exptl. investigation of the sensitivity characteristics to the surrounding refractive index (SRI) in thinned long period gratings for a wide range of fiber diams. and different low orders cladding modes. Wet chem. etching combined with microscopic anal. allow us to identify the exptl. dependence of the SRI sensitivity on the cladding radius.File in questo prodotto:
