A new structure of Long-Period Gratings (LPGs) sensor is introduced as a sensitive ambient RI sensor. This structure consists of creating periodic corrugations on the cladding of the LPG. The experimental results show that this LPG structure has good performances in terms of linearity and sensitivity and serves as a highly sensitive and cost-effective sensor. It also has the advantage of portability as the corrugation can also serve as the reservoir for the specimen collection to be tested.

In this work, we report a systematic investigation about the sensitivity of arc-induced Long Period Gratings in standard SMF28 fiber. Several gratings were fabricated with period Λ in range 330–630 µm and characterized towards changes in the surrounding refractive index (SRI), temperature and strain conditions. Wide tuning of the sensitivities is reported, with maximum values of -6391.7 nm/RIU, 95.5 pm/°C and 2.0 pm/με, respectively, for SRI, temperature and strain. These results permit the proper selection of the fabrication parameters in order to have the desired sensing features for a specific application.
