All-optical regeneration and wavelength conversion in an integrated semiconductor optical amplifier/distributed-feedback laser

Simultaneous all-optical regeneration and wavelength conversion is demonstrated at 2.488 Gb/s for the first time in an integrated distributed feedback laser/semiconductor optical amplifier. After 93 km of standard fiber, a negative sensitivity penalty of -1.3 dB is achieved upon wavelength converting all-optically from 1538 to 1553.5 nm.
