MAETTAD HALVLEDARLASERFOERSTAERKARE FOER KOMPENSERING AV OPTISK FIBERDISPERSION

摘要

The span of an optical dispersion-limited fiber (14) for propagating optical pulses is improved by simultaneously chirping and amplifying the stream by means of a saturated semiconductor laser amplifier (13). The chirp causes a compression of the pulses as they propagate through an initial portion of the fiber, whereby the span of the fiber is increased.
