In this thesis, we investigate the single-pumped
L-band (1570-1610 nm) amplified spontaneous
emission fiber source by employing 1480 nm single
pumping configuration. Using the 1480 nm-pumped
laser, we chose the adequate fiber length and
adjusted the pump power to optimize the
characteristics of the ASE source. The
characteristics are experimentally examined and
compared in terms of the output power, mean
wavelength, spectral linewidth, and pumping
conversion efficiency in four configurations with
single-pass forward (SPF), single-pass backward
(SPB), double-pass forward (DPF), and double-pass
backward (DPB) structures. Among them, the DPF
configuration with low mirror reflectance of 8%
is the better one to be an L-band ASE fiber
source with output power of 13.8 mW, mean
wavelength of 1585.7 nm, spectral linewidth of
40.9 nm and pumping efficiency of 13.8%.
