1. A method of generating light using a superfluorescent fiber source (SFS), the method comprising:

  • providing a SFS having a mean wavelength influenced by a pump light wavelength, the SFS comprising a doped fiber having a first end, a second end, and a length between the first end and the second end; and

    pumping the fiber with pump light from a pump source having a wavelength dependent on the temperature of the pump source and dependent on the power of the pump light, wherein the length of the fiber is selected to compromise between reduction of the dependence of the mean wavelength on the pump light power and reduction of the contribution of the forward amplified spantaneous emission light produced by the fiber to the output light.
