Sb-doped silica EDF showed an opposite temperature dependent gain profile compared to Al-doped silica EDF. Concatenation of those two EDFs showed a gain variation less than ?0.4 dB over 40nm of C-band with the 15dB ga...Sb-doped silica EDF showed an opposite temperature dependent gain profile compared to Al-doped silica EDF. Concatenation of those two EDFs showed a gain variation less than ?0.4 dB over 40nm of C-band with the 15dB gain, in the temperature range of- 40 to + 80℃.展开更多
