摘要: In this paper, we propose and demonstrate a technique to realize multiwavelength operation in erbium-doped fiber lasers (EDFLs) by inserting two Fabry Perot laser diodes (FP-LDs) the cavity respectively cascaded parallel way. The FP-LDs not only act as wavelength selection elements, but also offer optical gain or loss for wavelengths cavity. gains losses oscillation obtained from differ with adjustment of driving current FP-LDs. Thus, utilization can introduce dependent which effectively suppress competition caused homogeneous broadening (EDF). As result, 16-wavelength 20-wavelength wavelength-spacing 1.25 nm has been achieved based EDFL schemes. measured power fluctuation each is smaller than 0.4dB both EDFLs. Furthermore, injection locking ensures narrow linewidth output estimated be narrower 100 MHz scheme EDFL.
