All-optical modulation format conversion from NRZ-OOK to RZ-QPSK using integrated SOA Three-Arm-MZI wavelength converter

We demonstrate an error-free all-optical 2x10.7 Gb/s NRZ-OOK to 10.7Gsymbol/s RZ-QPSK modulation format conversion using a newly developed integrated SOA three-arm-MZI wavelength converter module.
