Long period fiber grating and high sensitivity refractive index sensor based on hollow eccentric optical fiber
Long period fiber grating and high sensitivity refractive index sensor based on hollow eccentric optical fiber
We have demonstrated experimentally a long period fiber grating (LPFG) written in a hollow eccentric optical fiber (HEOF). A high-quality LPFG with no structural deformation was fabricated using a highfrequency CO2 laser with a low energy density of 0.896 J/mm2. The LPFG writing parameters showed only a weak dependence on orientation of the fiber core to the writing beam. The liquid-filled HEOF LPFG has a high refractive index sensitivity of 1005 nm/RIU over a refractive index range of 1.422-1.441. The good performance and easy fabrication of the HEOF LPFG indicate that it is a promising platform for novel in-fiber microfluidic devices.

Abstract
We have demonstrated experimentally a long period fiber grating (LPFG) written in a hollow eccentric optical fiber (HEOF). A high-quality LPFG with no structural deformation was fabricated using a highfrequency CO2 laser with a low energy density of 0.896 J/mm2. The LPFG writing parameters showed only a weak dependence on orientation of the fiber core to the writing beam. The liquid-filled HEOF LPFG has a high refractive index sensitivity of 1005 nm/RIU over a refractive index range of 1.422-1.441. The good performance and easy fabrication of the HEOF LPFG indicate that it is a promising platform for novel in-fiber microfluidic devices.
