Abstract :
The authors report the generation of 20 GHz, 3.0-3.5 ps transform-limited optical pulses across the wavelength tunable range 1550-1557 nm using a wavelength tunable, polarisation-maintaining actively modelocked Er3+-doped fibre ring laser. Stable bit-error-free modelocking operation is confirmed throughout the wavelength tuning range.
