Abstract
An amplified spontaneous emission (ASE) source is proposed for use as a pump for fiber-based optical amplifiers and lasers. It is proposed to the ASE source in place of the conventional single-wavelength pump source. The ASE pump power can be generated using a simpler configuration than a conventional fiber-based laser source. Advantageously, it has been found that an ASE source of pump light may be as efficient as the conventional single-wavelength pump source in many applications. Furthermore, given the relatively high levels of pump power required for some applications, ASE pumping is thought to reduce the possibility that fiber nonlinearities (e.g., stimulated Brillouin scattering or Raman scattering) are triggered in the gain fiber.
