Abstract

Various example embodiments of a wavelength division multiplexing (WDM) direct detection (DD) system are presented. The WDM DD system may be configured to support WDM within the context of any WDM system supporting communication of wavelength channels based on modulation formats recoverable by direct detection (e.g., based on intensity-modulated (IM) signals within the context of a WDM IM-DD system, single-sideband (SSB) signals within the context of a WDM SSB-DD system, or the like). The WDM DD system may be configured to support WDM within the context of a WDM DD system, based on labeling of the wavelength channels with a set of states of spatial mode and polarization (SoSPs), based on use of an SoSP labeler on the transmit side to associate SoSPs with the wavelength channels and based on use of a receiver on the receive side to detect the SoSPs and recover the wavelength channels based on the SoSPs.
