Abstract :
We launch external-cavity feedback wavelength-tunable diode laser light into birefringent fibers and capture simultaneously the fiber cross-sectional images of two orthogonally polarized modes under various wavelengths. Through image analysis, we can obtain the refractive-index difference.
