We present a digital holographic microscope that permits one to image polarization state. This technique results from the coupling of digital holographic microscopy and polarization digital holography. The interference between two orthogonally polarized re ...
The precise determination of residual stress profiles in optical fibers allows drawing conclusions about radiation-induced density-changes of the fibers doped core glass. The corresponding index changes partially contribute to the phenomenon of photosensit ...
Among all scattering processes, spontaneous Brillouin scattering originates from the interaction between light and thermal acoustic waves propagating in the medium. The interference resulting from the incident light and its spontaneously backscattered frac ...
Two new simple interferometric methods for birefringence measurements are described applying to either low- or high-birefringence fibres and to any kind of birefringence, the set-up being free of a polarizing device. ...

We have experimentally studied polarization properties of the two-dimensional coupled photonic crystal microcavity arrays and observed a strong polarization dependence of the transmission and reflection of light from the structures-effects that can be empl ...
Single mode guided optics have recently taken a predominant place in communications systems. For instance single mode fibres enable long span, high data rate transmission links to be installed. In such fibers the data rate is ultimately limited by the chro ...
A method to determine the individual strain-optic coefficients in single-mode fibers is described. It is based on two photoelastic experiments, namely, the polarimetric measurement of optical activity induced by mechanical twist and the interferometric mea ...
A simple method for interferometric measurements of chromatic and polarization mode dispersion os single mode fibres and devices is presented. Accuracy of the method and resolution limits are discussed. ...
This paper presents a new method for writing and erasing a birefringence in optical fibers by polarized UV side-exposure. This experiment gives new insight into the origin of the induced birefringence and some applications are outlined ...
Birefringent single-mode fibers with random polarization mode coupling and polarization dependent losses are considered. The effect of these losses on polarization mode dispersion (PMD) is computed. The relevant number is found to be the differential loss ...
