Abstract
A wavelength-tunable 4×10 GHz optically modelocked semiconductor fibre ring laser is demonstrated. A semiconductor optical amplifier (SOA) is used as a gain medium and optically controlled mode-locking element, in addition to four superimposed linearly chirped fibre Bragg gratings to provide tunable, multi-wavelength operation. The four wavelengths can be tuned simultaneously with constant wavelength separation by changing the modulation frequency.
