Abstract

This paper presents the static behavior of Thulium-doped fiber amplifier (TDFA) operating around 2 μm at two different pump wavelengths. The model considers the influences of the amplified spontaneous emission (ASE) noise, the wavelength and the power of the seed, the thulium-doped fiber length and...
