Enabling optoelectronic technologies for optical networking

In this talk, we will discuss in detail the multiwavelength DFB laser array technologies, and the all-optical wavelength converter technologies. Two types of DFB laser arrays have been developed for the MONET wavelength add-drop multiplexers (WADM) and wavelength terminal multiplexers (WTM). Laser arrays are to be incorporated in the MONET WADM network and WTM networks. Amongst various proposed wavelength conversion techniques, we have investigated the parametric wavelength converter for difference frequency generation in a nonlinear waveguide. The unique feature of the parametric wavelength converter is that it can convert all wavelength simultaneously as it has been demonstrated recently.
