FIBER LOOP MIRROR FILTER WITH TWO-STAGE HIGH BIREFRINGENCE FIBERS [PDF]
Progress In Electromagnetics Research C, 2009 A flber loop mirror (FLM) with two-stage high birefrin- gence (Hi-Bi) flbers is theoretically and experimentally studied for var- ious rotation angles and Hi-Bi flber lengths. The experimental spectra are observed to be in good agreement with the theoretical spectra, ver- ifying our theoretical model.

Temperature-independent torsion sensor based on “figure-of-eight” fiber loop mirror [PDF]
, 2012 An interrogation sensor system combining the “figure-of-eight” fiber loop mirror using a single directional 3×3 fiber optic coupler was proposed. One fiber loop mirror was formed by inserting a length of high birefringent optical fiber at the input ports

A High-Birefringence Microfiber Sagnac-Interferometer Biosensor Based on the Vernier Effect
Sensors, 2018 We propose a high-sensitive Sagnac-interferometer biosensor based on theVernier effect (VE) with a high-birefringence microfiber. The sensitivity enhancement is achieved by utilizing two cascaded Sagnac interferometers.
