WAVE-GUIDING STRUCTURE WITH LASING PROPERTIES |
摘要 |
Optical wave guides, e.g. fibres, for use as photonic amplifiers have a path region partly or, preferably, wholly composed as a silica/germania glass with 0.1 to 5000 ppm mole of Er3+ as a lasing additive and alumina to adjust the bandwidth, the Ge:Al mole ratio being more than 2.8, e.g. 1:0.001 to 0.25. it is surprising that low amounts of alumina have a useful and significant effect on the lasing bandwith whereby frequency division multiplex is facilitated.
