Abstract

We investigated the effect of cladding etching on an arc induced long period fiber grating (LPFG). We compared the characteristics of the arc induced LPFG for changes in temperature, ambient refractive index and stress, i.e. between the etched and non-etched LPFG. The LPFG was etched using HF solution for 30 minutes and a red shift in wavelength was observed. We also found that the sensitivity of the LPFG increases after etching.
