Mode-locked lasers in InP active-passive integration platforms

In this paper we present an overview of results obtained with passively mode-locked lasers fabricated in standard InP active-passive integration platforms. The platforms allow to combine various components such as semiconductor optical amplifiers, passive waveguides, on-chip mirrors, tunable distributed Bragg reflector gratings and phase shifters on the same chip. In this paper we show how integration of these components inside the cavity allows to improve the performance of mode-locked lasers.
