Abstract :
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 simultaneously pumped 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.
