1. A device comprising:
- a waveguide for an optical signal;
a plurality of drop filters positioned to respectively extract a plurality of frequency components from an optical signal in the waveguide; and
a plurality of mosaics, each mosaic containing one or more tiles and an interface coupled to a corresponding one of the drop filters, wherein the interface directs an information signal base on the frequency component that the corresponding drop filter extracts from the waveguide.

Abstract
A photonic interconnect system avoids high capacitance electric interconnects by using optical signals to communicate data between devices. The system can provide massively parallel information output by mapping logical addresses to frequency bands, so that modulation of a selected frequency band can encode information for a specific location corresponding to the logical address. Wavelength-specific directional couplers, modulators, and detectors for the photonic interconnect system can be efficiently fabricated at defects in a photonic bandgap crystal. The interconnect system can be used for both classical and quantum information processing.
