A High Sensitivity Strain Sensor Based on the Zero-Group-Birefringence Effect in a Selective-Filling High Birefringent Photonic Crystal Fiber

open access: yesIEEE Photonics Journal, 2018
A selective-filling high birefringent photonic crystal fiber (SF-HBPCF) based Sagnac interferometer (SI) was demonstrated. The SF-HBPCF was achieved by infiltrating a high index liquid into two symmetrical air holes of the innermost layer of an index ...
