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 considerableExpand

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 impurityExpand

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 ofExpand

Stable single-frequency traveling-wave fiber loop laser with integral saturable-absorber-based tracking narrow-band filter.
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 aExpand

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) regionExpand

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 chemicalExpand

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 involvesExpand

Squamous cell carcinoma of the prostate following treatment with an LHRH–agonist: a rare case of transformation of adenocarcinoma of the prostate
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 andExpand

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 dopantExpand

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
