Ground-state and excited-state absorption spectra covering the wavelength range of 450-1050 nm are presented for erbium-doped silica fibers with four different core codopants: GeO(2), GeO(2)/B(2)O(3), GeO(2) /P(2)O(5), and Al(2)O(3). It is shown that

A detailed set of measurements is presented on determining the emission and absorption cross sections of Er3+ doped fibers for the 4 I 13/2 to 4 I 15/2 transition. Two techniques are employed: the Füchtbauer-Ladenberg analysis, based on spectroscopi
Optical fibre preforms, which have their germanosilicate core regions doped with small quantities of the rare-earth element erbium, have been studied using Extended X-ray Absorption Fine Structure Spectroscopy (EXAFS) at the germanium K absorption ed

We report on recent progress towards the application of both mixed cadmium halides and sulphide-based glasses as host materials for a Pr3+-doped 1.3 micron optical fiber amplifier. Both of these materials offer the potential for higher gains than can
It is shown that highly saturated, erbium-doped fiber amplifiers (EDFAs) can be employed as efficient power amplifiers. Differential pump-to-signal conversion efficiencies of 59% (quantum efficiency of 93%) can be obtained, resulting in 54 mW (+17.3

It has not been generally appreciated that the erbium-doped fibre amplifier1 (EDFA) has both a saturation output power which increases with pump power, as well as an ability to operate deep in saturation without signal distortion and interchannel cro

The fabrication and properties of 0.28 NA, 100/140 μm, multimode alumino-silicate fibre doped with 7.5 wt% Nd3+ is reported. These fibres show excellent potential for use as the sensing element in intrinsic optical fibre temperature sensors.

An optical amplifier consisting of an erbium-doped germanosilicate fiber optically pumped at 532 nm is described. Negligible excited-state absorption at 532 nm allows efficient pumping, enabling a gain of 34 dB at 1536 nm to be obtained for only 25 m
