SPECIAL OPTICAL FIBER Optical Properties (U Product Description YOEC polarization-maintaining photonic crystal fiber can be used in fiber optic gyroscope and polarization related devices, it has high radiation resistance, high birefringence effect and excellent temperature stability. The fiber has a large refractive index step between the air and the glass, which produces strong birefringence, which makes its beat length. Compared with the traditional polarization-maintaining fiber, the polarization-maintaining photonic crystal fiber can reduce the coupling between different polarization states caused by bending and maintain a large extinction ratio.
