Abstract
Laser sources are key components in any wavelength-division multiplexing (WDM) network. They should have low chirp because amplified WDM networks will involve long distances (hundreds of km) and operate typically at 2.5 Gbit/s per channel, and they should preferably also be wavelength selectable, with a robust adjustment scheme allowing from 8 to possibly >30 wavelength channels with 100 GHz separation.
