| High power two-section tapered lasers are promising candidates to generate short optical pulses by Q-switching. The main advantage of these devices is that high peak optical power can be generated by using a low excitation current in the ridge-waveguide section. In this work we analyze the Q-switching dynamics of two-section tapered lasers by means of a simplified three-rate-equation model and we compare the results with measurements in 1060 nm DBR multi/section tapered lasers. The experiments and simulations show similar trends with repetition frequency, modulation signal amplitude and bias conditions. The effect of the driving conditions on the peak power and pulse duration is analyzed. 100 ps pulses with 4.2 W peak power are obtained at 900 MHz repetition frequency. | |
