Abstract

In this paper, we present a noise figure improved double-pass L-band EDFA based on HiBi fiber loop mirror as the ASE suppressor. By utilizing a HiBi fiber loop mirror as the wavelength-dependent reflector, the ASE light has been weakened to a large extend, which increases the inversion ion population at the input end of erbium-doped fiber. Therefore, the noise figure of this double-pass EDFA has been much improved. Compared with that of the conventional double-pass structure based on 3dB fiber loop mirror, the NF of our novel configuration is reduced by 2.06-5.33dB for the ten sampled signal wavelength (1580.84nm-1588.48nm).
