All-optical wavelength conversion with monolithically integrated Mach-Zehnder interferometer SOA switches by selective area MOVPE

We achieved first dynamic all-optical wavelength conversion in bandgap-engineered MZI SOA all-optical switch. Clear eye-diagram of 2.5Gbps wavelength conversion was confirmed. This is the first wavelength conversion demonstration with a bandgap-engineered PIC with either selective-area-growth and quantum-well-intermixing techniques.
