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

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.
