Broad-band wavelength tuning (>60 nm) of 40 GHz actively mode-locked laser diode with external CW light injection

Broad-band wavelength tuning over 60 nm was successfully achieved in monolithic 40 GHz actively mode-locked laser diode with external CW light injection, remaining short pulse width (< 4 ps), low timing jitter of 0.18 ps, and low RIN value (< -130 dB/Hz).
