Paper Abstract

A novel L-band multi-wavelength erbium-doped fibre ring laser was proposed and studied by numerical method. The numerical model was developed based on a C-band EDFA and the propagation and rate equations of homogeneous broaden in two levels medium. In this L-band model, the excited state absorption was included during computing. The flat multi-wavelength laser in L-band was achieved by lengthening the erbium-doped fibre, and utilizing detrimental backward amplified spontaneous emission as a secondary pump power. The laser emitting spectral region was shifted, to prevent the mode competing at room temperature. This kind of laser can be useful in a wavelength division multiplexing transmission (WDM) system.
