| Description: |
An interconnection device based on an optical slab waveguide. |
|
| |
| Applications: |
Interconnection networks
On-chip/board interconnects
Multiprocessor interconnection networks
Network servers
Communication equipment
Holographic memories
Very efficient bus arbitration |
|
| |
| Advantages: |
Supports thousands of modes simultaneously
Admits millions of independent channels, each operating in the GHz range or higher
Each channel can support a loading of 1000 or higher
Novel "mode division multiplexing" allows channel densities, communication bandwidths, and flexibility unmatched by existing systems. |

| Abstract: | Optical slab waveguides are used as high-speed, high-capacity interconnects for parallel or other devices. Optical slab interconnects can connect to many more elements than can conventional electrical or fiber optic buses. A multiplexing scheme called "mode division multiplexing" greatly increases the number of independent channels that a single slab can suppport. Optical slab waveguides have a potential capacity of over one million independent channels, each channel operating at 1 GHz in a single physical medium, with each channel capable of receiving input from over 1000 ports and sustaining a load of over 1000. |
