Abstract
An FPGA is described using optical waveguides for routing signals through the FPGA. The routing is controlled electrically. Either coupling waveguides or resonant disks can be used for routing the optical signals. Lookup tables convert optical input signals to electrical signals for selecting values in the lookup table.
