Abstract
The development of powerful sources with wide spectral coverage is important for many sensing applications. In this paper, various superfluorescent fiber sources (SFS) at 1μm Wavelength using Ytterbium doped (Yb-doped) fiber is studied. Different configurations such as single pass forward (SPF), single pass backward (SPB), double pass forward (DPF), double pass backward (DPB), are compered in terms of spectral bandwidth, power, central wavelength stability and power stability. Double-pass bi-directional sources are employed using loop mirrors. For all cases, maximum power is compared at various laser diode power. Mean wavelength stability is measured between temperature of -40/+60°C to assess potential applications.
