J. Mangeney et al., System application of 1.5 mu m ultrafast saturable absorber in 10Gbit/s long-haul transmission, ELECTR LETT, 36(20), 2000, pp. 1725-1727
A semiconductor saturable absorber based on a heavy-ion-irradiated quantum
well vertical cavity is implemented in a 10Gbitis RZ loop transmission. Ind
uced reduction of amplified spontaneous emission accumulation is experiment
ally demonstrated for the first time to improve the error-free transmission
distance by a factor of 2.5.
