System application of 1.5 mu m ultrafast saturable absorber in 10Gbit/s long-haul transmission
28 September 2000
A semiconductor saturable absorber based on a heavy-ion-irradiated quantum well vertical cavity is implemented in a 10Gbitis RZ loop transmission. Induced reduction of amplified spontaneous emission accumulation is experimentally demonstrated for the first time to improve the error-free transmission distance by a factor of 2.5.
