Research output: Contribution to journalArticlepeer-review


Wavelength conversion via cross-gain modulation is demonstrated for the first time at 40Gbit/s in a distributed feedback laser monolithically integrated with a semiconductor optical amplifier. A bit error rate penalty of 2.2dB at 10-9 is reported for the operation.
