Abstract
The authors show that by coupling the output from a gain-switched DFB laser to a fibre loop mirror the spectral quality of the gain-switched pulse can be greatly improved. The SMSR of a gain-switched 1.5 mu m D FB has been increased by 25dB, and also the chirp has been-reduced, by using this technique. This spectral improvement is vitally important in systems where the gain-switched pulses will pass an optical filter.
