The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Interferometric Fiber Optic Sensors (2012, methodology): “An RI sensor based on the MZI composed of a pair of LPGs has been also reported [46], where the sensitivity of the cladding mode to the RI change in the surrounding medium was utilized.”
Fiber-taper seeded long-period grating pair as a highly sensitive refractive-index sensor (2005, methodology): “based on an LPG pair (LPGP) [5], [6] and the Michelson interferometer based on an LPG with a metal-coated fiber tip”
Low-cost optical fiber refractive-index sensor based on core diameter mismatch (2006, background): “Such an interaction length is nearly an order of magnitude shorter than that of RI sensors based on FBGs or LPGs.”
Towards a Uniform Metrological Assessment of Grating-Based Optical Fiber Sensors: From Refractometers to Biosensors (2017, methodology): “Very few of them account for the real resolution calculated using Equation (4) [28,51,57].”
