Generation of interleaved pulses on time-wavelength grid by actively modelocked fibre laser

The generation of successive pulses at different wavelengths is demonstrated in an actively modelocked fibre laser. The time and wavelength spacings between emitted pulses are controlled by insertion of a phase modulator and a fibre Mach-Zehnder, respectively. Three-wavelength operation at an aggregate rate of 9.4 GHz is reported.
