Abstract :
The temperature dependence of the gain of aluminosilica and fluoride based erbium-doped fiber amplifiers are theoretically and experimentally examined and compared. As expected from the larger temperature dependence of erbium-doped fluoride fibers (EDFB) cross sections, the single channel gain of EDFF amplifiers presents larger wavelength-dependent temperature sensitivity. The implications of this large and nonuniform temperature dependence of the gain on wavelength-division multiplexing (WDM) are theoretically analyzed and discussed
