We report effective all-optical multicast wavelength conversion exploiting cross gain modulation (XGM) in a QD-SOA. 80 Gb/s multi-conversion on four 400 GHz spaced wavelengths is demonstrated with moderate Q2 factor penalty.
We report regenerative amplification of 10, 40 and 80 Gb/s return-to-zero (RZ) signals in a columnar quantum dot SOA (CQD-SOA). Self-phase-modulation (SPM) with a red-shifted band-pass filter and limiting amplification are exploited.
