Abstract
A broadband light source is fabricated from an optical transmission medium having an amplification material such as rare earth doped (e.g. erbium) fiber. The natural emission spectrum of this amplification material is corrected. The weak emission wavelength region has been enhanced and the whole spectrum flattened. The source outputs high power with about 25% pump efficiency. The spectrum is stable and the power density is equalized through out the emission region.
