Abstract

Long period grating with a grating period of 15 μm is fabricated with a femtosecond laser. Such a small period grating enables coupling of fundamental core mode with high order cladding modes that have effective refractive index close to water, and exhibits an enhanced sensitivity in low refractive index region.
