Refractive index sensor based on the nanofilm coated double cladding fiber

Abstract

A refractive index sensor was proposed by using the nanofilm coated double cladding fiber (DCF). The DCF has a resonant filtering transmission spectrum due to the depressed refractive index inner cladding. To modify the resonant cladding mode of the DCF, a nanofilm with high refractive index was coated on the DCF by using atomic layer deposition technology… (More)
