Abstract
A coupling-ratio controlled wavelength tunable L-band erbium-doped fiber laser with tuning range of 45nm (1567 - 1612 nm), quantum efficiency of 42%, power conversion efficiency of 37%, tuning resolution of 0.3 nm is reported. The wavelength-tuning is achieved by a tunable band-pass filter (TBPF) or by adjusting the tunable-ratio optical coupler (TROC) without TBPF because of the difference of intracavity loss. The output wavelength can be tunable in the full L-band with TBPF, from 1567 to 1612 nm, and the pulse-width is <14.2 ps. Specially, during the wavelength-tunable process without TBPF, the modulation frequency of about 1 GHz remains unchanged and near-transform-limited pulses are generated by linear compression with 32.5 m single mode fiber (SMF) under 10% output coupling ratio.
