Birefringence and polarisation dispersion measurements in high-birefringence single-mode fibres

Electronics Letters, 1987
We have measured by white-light crosscorrelation the polarisation mode dispersion of a polarisation-maintaining single-mode fibre and its variation with wavelength. The results have been confirmed by birefringence measurements and by birefringence modelling.

Polarized light imaging of birefringence and diattenuation at high resolution and high sensitivity [PDF]

Journal of Optics, 2013
Polarized light microscopy provides unique opportunities for analyzing the molecular order in man-made and natural materials, including biological structures inside living cells, tissues, and whole organisms. 20 years ago, the LC-PolScope was introduced as a modern version of the traditional polarizing microscope enhanced by liquid crystal devices for ...
