Abstract :
A Sagnac interferometer integrated with a parallel-amplifier structure (SIPAS) is proposed for filter-free all-optical wavelength conversion. A Mach-Zehnder interferometer with a semiconductor optical amplifier in each arm is monolithically integrated with a Sagnac interferometer. Clear eye opening and low power penalty of 0.9 dB were achieved at a bit rate of 10 Gbit/s using the fabricated SIPAS.
