A wideband spectrum-sliced ASE source is demonstrated using a 1480nm pumped Bismuth-based Erbium-doped fiber and a thermal controlled fiber loop mirror. The spacing of output comb can be tuned by adjusting the birefringence and the effective length of the Polarization Maintaining Fibers (PMFs) in the loop mirror. By changing the temperature of the PMF segments, the spacing can be tuned from 1.69nm to 4.35nm corresponding to a number of channels of 52 to 21 within a wavelength range from 1530nm to 1620nm as the birefringence axis for both PMFs is adjusted to be perpendicular to each other.
