Full bit-rate conversion from 10-Gb/s random WDM channels to a 40-Gb/s channel using a Sagnac interferometer integrated with parallel amplifiers structure

Full bit-rate conversion from 10-Gb/s random WDM channels to a 40-Gb/s channel, including NRZ to RZ format conversion and reconversion, as well as phase adjusting procedure, is successfully demonstrated. Wavelength conversion in a monolithic Sagnac Interferometer integrated with Parallel Amplifiers Structure (SIPAS) is used.
