This paper compares the environmental sensing behaviour of long period gratings written in three fibers with different refractive index profiles: step, W and a progressive three layered fiber. The measurands considered are temperature, refractive index, axial strain and bending, and the spectral beh
## Abstract A longβperiod grating (LPG) written in the cladding of an optical fiber is demonstrated.The optical fiber is specially designed and manufactured, which cladding is photosensitive, and core is not~.~ The cladding LPG is written in by illuminating a cladding photosensitive fiber with an U
