Monolithically integrated widely tunable 40Gbits/s wavelength converter with optical label modulation function

What we believe to be a novel monolithically integrated wavelength converter consisting of a sampled grating distributed Bragg reflector laser, a long semiconductor optical amplifier (SOA), and a delayed interferometer Mach-Zehnder interferometer (DIMZI) is reported. Error-free 40Gbits/s wavelength conversion for three different probe wavelengths is demonstrated. The impact of the output filter bandwidth and filter detuning on the performance of wavelength conversion is studied in detail. The optical label modulation of the on-chip DI-MZI is first demonstrated with amplitude- and phase-shift key schemes.
