Mode Characteristics and Sensing Performance of Fiber Gratings
Journal of Harbin University of Science and Technology, 2022 Fiber gratings are special optical fibers with a periodic refractive index distribution when the refractive index of the fiber core is modulated. Both the angle and period of the gratings have an influence on the sensing properties of the fiber gratings.

Plasmonic crystal enhanced refractive index sensing [PDF]
Applied Physics Letters, 2014 We demonstrate experimentally how the local anisotropy of the dispersion relation of surface plasmon modes propagating over periodic metal gratings can lead to an enhancement of the figure of merit of refractive index sensors. Exploiting the possibility to acquire defocused images of the Fourier space of a highly stable leakage radiation microscope, we
