| 摘要 |
The present invention provides an optical system for decoding, switching, demultiplexing, and routing of optical encoded data signals across multiple decoding, switching, demultiplexing, and routing layers, including: a plurality of demultiplexing systems, each of the demultiplexing systems includes an input and a plurality of outputs, each of the demultiplexing systems is a system for performing a function selected from a group of functions including decoding, switching, demultiplexing, and routing for producing decoded signals at the outputs in response to the encoded data symbols received at the input; and a coupling mechanism for optically coupling the input of one demultiplexing system of the plurality of demultiplexing sytems to one of the outputs of another demultiplexing system of the plurality of demultiplexing systems to form a cascade of demultiplexing systems.
