Wavelength conversion, regeneration and tone manipulation using integrated semiconductor lasers and amplifiers

Wavelength conversion has been shown to provide an essential flexibility for managing an efficient, reconfigurable wavelength division multiplexed (WDM) network. An integrated SOA/DFB laser has shown promise as a simple all-optical wavelength conversion device together with useful simultaneous functions such as 2R regeneration and the ability to remove a wavelength identifying tone. Wavelength conversion performance at 20Gb/s and 40Gb/s will also be presented at the conference, in addition to a review of the current field.
