ABSTRACT:
Various embodiments of the present invention are directed to photonic interconnection architectures that provide high-speed interconnections of microscale or nanoscale devices. In one embodiment of the present invention, a photonic interconnection for interconnecting and synchronizing operation of components within a computing device comprises an optical transmission path for transmitting a number of independent frequency channels within an optical signal provided by an optical signal source. The photonic crystal may include one or more filters located near the waveguide for extracting specific frequency channels transmitted by the waveguide, the frequency channel including one or more frequency channels carrying a clock signal. One or more photodetectors positioned near the one or more filters 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.
