Abstract

New coding and modulation techniques formulated specifically for employment with wavelength division multiplexing (WDM) components and systems to significantly increase the number of virtual channels are described and analyzed. It is generally accepted that technical and economic considerations limit a conventional WDM system to less than 32 wavelength channels and, in the near term, most likely to 4 or 8. We assume a 4-wavelength WDM system and impose WDM coding or modulation in which the WDM wavelengths are interpreted as unit vectors in a quasi-orthogonal space. We describe how various combinations of these unit vectors define signatures of the wavelength-space type (WDM-vectors), the wavelength-space-time type (WDM-matrices), or the hybridized WDM-optical CDMA type, each potentially capable of yielding a rich address space, even when the number of WDM wavelengths is small. The topologies, implementation, and performance of these codes is discussed for network and interconnection systems.
