Patent ID: 7359587

Claim:
A photonic interconnection for interconnecting and synchronizing operation of components within a computing device comprising: an optical transmission path for transmitting a number of independent frequency channels within an optical signal provided by an optical signal source; one or more filter resonant cavities of a photonic crystal located near the optical transmission path, each filter resonant cavity extracting one of one or more specific frequency channels transmitted by the optical transmission path via evanescent coupling, the frequency channels including one or more frequency channels carrying a clock signal; and one or more photodetector resonant cavities of the photonic crystal, wherein each photodetector resonant cavity is positioned adjacent to one of the one or more filter resonant cavities and includes two electrodes in order to extract specific frequency channels from the adjacent filter resonant cavities via evanescent coupling and convert the extracted frequency channels into electrical signals for use by one or more components of the computing device, the electrical signals including one or more clock signals for synchronizing operation of the one or more components.
