Abstract :
Using sinusoidal waveform, an InGaN laser unit which incorporated a 50-Omega impedance-matching unit was used to generate <70-ps pulses with a repetition frequency ranging from 800MHz to 3.0 GHz. At 1.0 GHz, the pulses with a pulsewidth of 31ps and a peak power of >450 mW were obtained using +27dBm of RF power. Tuning characteristics of this gain-switching laser were studied
