LBand BismuthBased ErbiumDoped Fibre Amplifier: Experimental evaluation of a new host material for Erbiumdoped Fibre Amplifi,Used
Delivery time: 8-12 business days (International)
Characterization study of Bismuthbased Erbiumdoped Fibre (BiEDF) and its performance as gain medium for Lband Erbiumdoped Fibre Amplifier (EDFA) is studied. Bismuth oxide glass host enables very high erbium doping concentration without significant concentration quenching effect. The BiEDF studied is only 2.15m long with Erbium ion concentration of 3,250 wt. ppm. corresponding to a maximum absorption coefficient of 157.61dB/m at 1530nm. With optimum excitation, BiEDFA exhibits small signal gain bandwidth of over 70nm ranging from 1550nm to 1620nm. Maximum signal gain per length coefficient at 1580nm for BiEDFA is 12.7dB/m. A 56nm 3dB gain bandwidth with average gain of 18.6dB is achieved. Improvement on the small signal gain performance of BiEDFA is demonstrated in a twostage EDFA configuration. By utilizing Cband ASE generated by BiEDFA as pump source for a second stage EDF, maximum small signal gain improvement of 5.0dB over the single stage BiEDFA is observed.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
