Plastic optical fibers,Polarization-Maintaining Characteristics
For the sensing applications of large-core plastic optical fibers (POFs), suppressing birefringence changes caused by external stress remains a challenge. In this study, POFs with a conventional composition using a zero-zero birefringence terpolymer and a high-NA core composition were fabricated, and their stress characteristics were compared. The high-NA core exhibited a phase shift of 80° per unit length under an applied load of 500 N. Future work will focus on controlling the photoelastic constant based on the conventional composition, which excels in suppressing phase shifts, to establish zero-zero birefringence POFs.
