Abstract

A long period fibre grating written in a progressive three-layered optical fibre is shown to exhibit an attenuation band that has a very low bending sensitivity (5.1×10 –2 nm m) compared to normal step-index fibre, and is also insensitive to changes in the refractive index of the surrounding medium. Applications to sensing and telecommunications are discussed.

Uncontrolled Keywords: long period fibre grating, progressive three-layered optical fibre, attenuation band, bending sensitivity, refractive index
