Abstract

Different optical multiplexing techniques are described for providing parallel, high-speed communication between multiple nodes in a distributed multi-access network. Using compact, 2D arrays of VCSELs and VCSEL-based optical switches, data from different nodes can be multiplexed together in the space, time, or wavelength domain, and then transmitted through a single optical fiber. Each channel can be individually-modulated, time-compressed, and time- multiplexed in a bit-serial fashion into a single, high-speed data stream, while different channels are wavelength-multiplexed on a single optical fiber. Spatial routing is achieved by a distributed optical switching network, in which space and wavelength can be combined to provide wavelength routing without wavelength tuning.
