Abstract :
Monolithically integrated electroabsorption modulated laser grown by selective-area epitaxy using MOVPE is a very essential source for multigigabit long-haul WDM transmission systems employing EDFAs. Such an EML offers very low chirp, low drive voltage, long-term reliability and compact size.<>
