ABSTRACT
A linear self-reference spectral interferometry has been proposed to measure the distribution of polarization-maintaining photonic crystal fiber (PM-PCF) birefringence over a wide wavelength range combined with the soliton self-frequency shift and birefringence effect. The birefringence of PM-PCF is measured experimentally over the range of 800-970 nm, which is larger than 5×10-4 and shows a segmented change trend. The air micropore structure has a significant effect on the characteristics of PM-PCF, which makes it have a highly nonlinear coefficient, and at the same time, changes the dispersion and birefringence distributions of the PM-PCF. The distribution of PM-PCF birefringence, measured by experiment, provides a new dimension for the design of PM-PCF, which is helpful for a detailed fiber model and an iterative optimization of fiber structure.
