摘要：
The sub-picosecond gain dynamic in a highly index-guided tapered-waveguide laser diode amplifier is studied. The analysis is based on a set of rate equations for the carrier density N and carrier temperature T, where the effects of lateral distributions of both N and Tare considered. It is found that both N and T have significant effects on the gain dynamic of the tapered-waveguide laser diode amplifier. The gain saturation of the tapered-waveguide amplifier for both 20 ps and 200 fs pulses is also calculated.
