Summary:This paper describes the operating principle, structure, fabrication technology, and basic characteristics of newly developed wavelength converter named SIPAS. In SIPAS, a Mach-Zehnder interferometer with semiconductor optical amplifier in each arm is monolithically integrated with a Sagnac interferometer. Filter-free wavelength conversion with output pulse width of 13 ps due to differential-phase-modulation was achieved using the fabricated SIPAS. The power penalty was as low as 0.9 dB at a bit rate of 10 Gbit/s. All-optical 3R that retains input wavelength is also demonstrated using SIPAS at a bit rate of 40 Gbit/s.
