We describe the application of spatially resolved cathodoluminescence on three samples of MCVD preforms and three MCVD fibres which led to results on fibres in contradiction with those of Atkins et al.

In some currently deployed terrestrial transmission systems, amplifiers must cope with long-term capacity upgrades by ensuring a gain bandwidth exceeding 30 nm and a noise performance close to 5 dB. A complex 980-nm/1480-nm pumped hybrid structure (H

The authors demonstrate that single stage phosphorus-aluminium-codoped EDFAs greatly increase the usable spectral bandwidth for long-haul submarine applications. With such an amplifier, a total gain excursion of 5 dB was measured for eight WDM channe

A parametric study on the depressed inner cladding (DIC) single-mode fibers shows the influence of the inner-cladding diameter on the effective cutoff wavelengths of the first two modes, determining a practical transmission window. The set of curves

Optical and ESR measurements have been performed on Cr doped PbMoO 4 single crystals. A linear correlation has been established between the chromium concentration and the intensity of the color-inducing 430 nm band. From ESR results, a mechanism invo

Fiber drawing conditions (temperature, speed, tension) have been investigated to reach very low losses (0.20 dB/km at 1.55 μm) with MCVD triangular core-profile preforms. Such dispersion-shifted fibers exhibit good mechanical, splicing, cabling, and

Easy handling flexible mid-IR light conductors have been made of GeAsSe chalcogenide glass fibers coated with polyolefin. Optical transmission level is about 10 dB/m in the 4 - 11 micron band. Few watts of CO2 laser power may be transmitted.

MCVD preforms with a doped core are known to have a central index depression which can have a noticeable influence on the fiber transmission properties. The magnitude of the dip can be reduced by carrying out an etching treatment with a fluorine comp
