One of the keys to viable WDM systems is the availability of inexpensive low-chirp optical transmitters at 1.55 /spl mu/m. By taking advantage of photonic integrated circuit technology, it is possible to produce monolithically integrated DFB or DBR laser/electroabsorption modulators (EMLs) with low chirp, low drive voltage and high extinction ratio, in a single compact package. 2.5 Gbit/s EMLs have recently become commercially available, and prototype 10 Gbit/s EMLs are available for system experiments.
