Abstract :
The influence of bending on gain spectrum in a depressed-cladding erbium-doped fiber amplifier has been studied. In particular, by changing the bending diameter, it is possible to translate the amplifier band from C- to S-band. As a consequence, a 22 dB gain has been obtained in S-band at 1504 nm for a bending diameter of 15 cm and an input signal power of -15 dBm, while a peak gain of 21.9 dB has been obtained in C-band at 1545 nm for a bending diameter of 100 cm and the same signal power.
