A new S-band erbium-doped fiber amplifier module with a double-pass configuration based on two circulators has been designed and constructed. The bending losses of a depressed-cladding doped fiber have been exploited to suppress the amplified spontaneous emission in the C band. The experimental characterization of the double-pass amplifier has shown that significant advantages can be obtained with respect to the single-pass configuration.

Abstract
A new S-band erbium-doped fiber amplifier module with a double-pass configuration based on two circulators has been designed and constructed. The bending losses of a depressed-cladding doped fiber have been exploited to suppress the amplified spontaneous emission in the C band. The experimental characterization of the double-pass amplifier has shown that significant advantages can be obtained with respect to the single-pass configuration.| File | Dimensione | Formato | |
