Popis: We report on the fabrication and characterization of a new device, named IRIS. It is designed to increase the coherent optical bandwidth of a picosecond pulse train for subsequent pulse compression. The IRIS device consists of a concatenated array of semiconductor optical amplifiers and saturable absorbers. It is realized in the InP/InGaAsP material system for the 1550 nm range. Measurements on the realized IRIS devices show increased broadening of the pulse spectrum as compared to an SOA of equivalent length and a smoother optical power spectrum. Consequent compression of the chirped pulses using standard single mode fiber shows decreased pulse pedestals as compared to an SOA, indicating increased linearity of the chirp. Pulse compression up to 50 % is observed.
