Correlation between emission and relative intensity noise spectral profiles of an Er-doped fiber superfluorescent source

AIP Advances, 2022
The spectral characteristics of the relative intensity noise (RIN) of two amplified spontaneous emission (ASE) sources are experimentally measured. An Er-doped fiber superfluorescent source (EDF-SFS) is investigated and compared with a super-luminescent ...

Dual-wavelength domain wall solitons in a fiber ring laser

, 2010
We report on the experimental observation of a new type of dark soliton in a fiber laser made of all normal group velocity dispersion fibers. It was shown that the soliton is formed due to the cross coupling between two different wavelength laser beams ...
