The mechanical resistance of UV irradiated optical fibers has been investigated by dynamic fatigue tests. The intrinsic Weibull distribution of the pristine and chemically stripped fiber were almost identical. The high germanium doped fiber was homogeneous ...
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 ...
We present two interferometric techniques for the measurements of the polarization mode dispersion of standard (i.e. circular) single-mode fibers. The first method uses an interferometric loop and works in the frequency domain. The second uses a polarizati ...
Dispersion supported transmission (DST) is a new technique which combines intensity modulation (IM) and optical frequency modulation (OFM) to allow transmission spans beyond the usual dispersion limit. Using computer simulation, DST limitations are evaluat ...

A novel approach, called pigtailing, is presented for the construction of optical detectors for capillary electrophoresis. Optical components and procedures from other fields, mainly telecommunications, are incorporated into these devices to give miniaturi ...
All-fiber optical phase modulators were fabricated by coating standard telecommunication optical fibers with thin films of piezoelectric ZnO. Piezoelectric optical fiber coatings of PbZrxTi1-xO3(PZT) were also produced, and the actuation capability necessa ...
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 ...
Permanent Bragg gratings in monomode optical fibers are obtained by irradiation through an interference pattern of an ultraviolet laser. The main parameters of such gratings, in particular the index modulation amplitude and their length, are precisely dete ...
Polarization dispersion is an effect which may cause data rate penalty in optical links. This is caused by the combined effect of fibre birefringence and polarization couplings due to environmental perturbations. Polarization dispersion is therefore a stoc ...
