Theoretical Research on the Strain Characteristics of the Selective-Filling Birefringent Photonic Crystal Fiber

In this paper, the detailed strain characteristics of a selective-filling birefringent photonic crystal fiber (SF-PCF) were analyzed theoretically. The SF-PCF was achieved by selectively filling two symmetrical air holes around the fiber core of a PCF with a high index liquid. The group birefringence and phase birefringence presented unique characteristics different from the traditional index-guiding birefringence fiber. Hence, the transmission and sensing characteristics of the Sagnac interferometer based on the SF-PCF presented diversity and high sensitivity. Finally, the highest strain sensitivity of −9.56 pm/μe was theoretically achieved.
