Spectral encoding of an optical label or destination

摘要

An apparatus comprising a processor, wherein the processor is configured to to determine a plurality of available wavelengths that are available to transmit data over an optical network comprising a plurality of downstream nodes, select a plurality of encoding wavelengths from the available wavelengths, wherein the encoding wavelengths is a subset of the available wavelengths, and encode the data using the encoding wavelengths, wherein the encoding wavelengths dictate the switching behavior of the downstream nodes when the data is received by the downstream nodes.

主权项

1. An apparatus comprising:
a splitter configured to split an optical signal into a first optical portion and a second optical portion; a Fourier Transform Unit (FTU) configured to perform a spectrum analysis on only the first optical portion to produce the power spectrum data for the first optical portion; a control logic unit coupled to the FTU, wherein the control logic unit is configured to use the power spectrum data to provide a routing instruction; and an optical switching unit coupled to the control logic unit, wherein the switching unit is configured to route the second optical portion using the routing instruction, wherein the FTU comprises a plurality of resonator rings configured to produce the power spectrum data.
