80 nm Spectrally-Flattened, High Power Erbium Amplified Spontaneous Emission Fiber Source
20 July 2000
We report a novel two-stage spectrally-flattened, high output power erbium amplified spontaneous emission (ASE) fiber source pumped using a single laser diode pump. The source has a spectrally flattened bandwidth of 80 nm with an output power of +13 dBm (20 mW). We used long period gratings to flattened the ASE spectrum to within 1 dB over the 80-nm bandwidth.
