Abstract :
Wavelength switching is demonstrated in an actively modelocked fibre laser containing an arbitrary number of fibre Bragg gratings. The switching is realised by electrical control of the delay time between two RF signals driving the cavity modulators. Electrical switching among five different wavelengths has been achieved with an extinction ratio of >40 dB
