Birefringence and polarization mode-dispersion in spun single-mode fibers.
A theoretical and experimental analysis of the polarization properties of twisted single-mode fibers is presented. It is shown that whereas a conventionally twisted fiber possesses considerable… Expand
Fabrication and characterization of low-loss optical fibers containing rare-earth ions
Low-loss fibers containing rare-earths have been produced with high absorption levels in the visible and near infrared regions. Although containing relatively large quantities of rare-earth impurity… Expand
Mode conversion coefficients in optical fibers.
A simple method has been devised for the experimental determination of mode conversion coefficients in multimode fibers and involves only the observation of the far-field output as the angle of… Expand

We demonstrate stable single-frequency and polarization operation of a traveling-wave, Er(3+)-doped fiber loop laser by incorporating an unpumped Er(+3)-doped fiber section butted against a… Expand
Photodarkening in Yb-doped aluminosilicate fibers induced by 488 nm irradiation
Photodarkening of Yb-doped aluminosilicate fibers by continuous wave 488 nm irradiation was investigated. The irradiation induced significant excess loss in the UV-visible spectroscopy (VIS) region… Expand
MCVD in-situ solution doping process for the fabrication of complex design large core rare-earth doped fibers
We report on the fabrication and characterization of rare-earth doped silica fibers manufactured using an in-situ solution doping technique, which is compatible with conventional modified chemical… Expand
Determination of core diameter and refractive-index difference of single-mode fibres by observation of the far-field pattern
A method is described for determining unambiguously, from the far-field pattern of single-mode fibres, the core diameter and the refractive-index difference between core and cladding. It involves… Expand

Squamous cell carcinoma (SCC) is a rare variant of prostate cancer. We report a case of a patient who was diagnosed with metastatic adenocarcinoma of the prostate, treated with leuprorelin and… Expand
Solution-doping technique for fabrication of rare-earth-doped optical fibres
A solution-doping technique is reported for the reproducible fabrication of low-loss optical fibres containing up to 4000 parts in 106 of rare-earth ions. The method produces excellent dopant… Expand
Zero material dispersion in optical fibres
The material dispersion of optical fibres having cores of silica or phosphosilicate glass falls to zero at a wavelength between 1.2 and 1.3µm. A considerable increase in bandwidth can be obtained,… Expand
