Small-period long-period fiber grating with improved refractive index sensitivity and dual-parameter sensing ability [PDF]

, 2017
We UV inscribe and characterize a long-period fiber grating with a period of 25 μm. A series of polarization-dependent dual-peak pairs can be seen in the transmission spectrum, even though only the symmetrical refractive index modification is introduced.
