Abstract :
We first demonstrate amplification in EDFA at wavelengths of 1489-1519 nm using a multi-stage configuration of silica-based EDF (erbium doped fiber) and ASE (amplified spontaneous emission) suppressing filters. The Raman/EDFA hybrid amplifier realizes a useful S-band optical amplifier with dispersion compensation and low non-linearity.
