Mason, PL and Wonfor, A and Marcenac, DD and Moodie, DG and Brierley, MC and Penty, RV and White, IH and Bouchoule, S (1997) Effects of pedestal suppression on gain-switched laser sources for 40 Gbit/s OTDM transmission. In: UNSPECIFIED pp. 289-290..Full text not available from this repository.
The performance of 40 Gbit/s optical time-division multiplexed (OTDM) communication systems can be severely limited when the extinction ratio of the optical pulses is low. This is a consequence of the coherent interference noise between individual OTDM channels. When taken alone, the multiple quantum well-distributed feedback laser+dispersion compensating fiber source exhibits a relatively poor extinction ratio which impairs its potential for use in a 40 Gbit/s OTDM system. However, with the addition of an electroabsorption modulator to suppress the pulse pedestals to better than 30 dB extinction, coherent interference noise is reduced, the bit-error-rate performance is greatly improved, and the source shows good potential for 40 Gbit/s OTDM communication.
