Abstract
Direct frequency modulation of a DFB laser followed by FM to IM conversion in an interferometer is a promising technique to produce low chirp transmitters to be used in high speed direct detection systems. In this paper, the performance of FSK-IM systems operating at 10 Gb/s is analyzed, and the sensitivity and the linewidth requirements are estimated. A comparison between FSK-IM systems and FSK heterodyne systems is also performed, showing that for 1 dB sensitivity penalty, the linewidth requirements for heterodyne systems are higher.
