Ultrafast InP optical integrated circuits

In this paper we first present a brief overview of our work on indium phoshide integrated optical circuits. Integrated circuits can be produced that contain active components such as optical amplifiers and passive component such as waveguides, arrayed waveguide gratings and phase modulators. With this set of components complete laser systems can be designed and realized on a chip. Then we will present in what way our integration technology can be used to generate and utilize ultrafast optical pulses. Issues concerning the realization, operation and future developments will be discussed.
