Abstract
By using the technique of quantum-well intermixing (QWI), monolithical ly integrated passive, and active waveguides can be fabricated. It is shown that mode-locked extended cavity semiconductor lasers with integ rated low-loss passive waveguides display superior performance to devi ces in which the entire waveguide is active: the threshold current is a factor of 3-5 lower, the pulsewidth is reduced from 10.2 ps in the a ll active laser to 3.5 ps in the extended cavity device and there is a decrease in the free-running jitter level from 15 to 6 ps (10 kHz-10 MHz).
