SOA-pumped erbium-doped ASE fibre source with flattened spectrum and high power density

摘要

A spectrum-flattened two-stage amplified spontaneous emission (ASE) fibre source is proposed and experimentally demonstrated. The source is structured by an erbium-doped fibre simultancously pumpcd by a 980 nm laser and a semiconductor optical amplifier (SOA) source. In the wavelength range of 1526-1563 nm, a spectrum ripple of ± 0.5 dB and an average power density of - 14 dBm/0.1 nm are achieved.
