Abstract

One embodiment of the present invention provides a system for the transmission of data between an optical bus and an electronic component at a speed independent from a clock speed of the electrical component; the system comprising an optical data storage component communicating with both the optical bus and the electrical component; the optical data storage component being configured to hold data transmitted on the optical bus until said electrical component is available.

Claims

1. A system for interface between an optical bus and electronic component, the system comprising:

an optical transfer array for receiving and transmitting data to and from said electronic component;

an optical decode/encode matrix reading data transmitted from said electronic component uploaded to said transfer array, and writing control data to switches disposed within the transfer array and providing a plurality of addresses for optical guides in said optical bus.

2. The system of claim 1 wherein said transfer array further comprises a plurality of optical latches controlled by said switches, said optical latches being configured to store said data until it can be retrieved by said optical bus.

3. The system according to claim 1 wherein said optical bus is a serial bus.

4. The system according to claim 1 wherein said optical bus is a parallel bus.

5. The system according to claim 1 wherein said latches within said plurality of optical latches comprise first and second interferometers.

6. A system for the transmission of data between an optical bus and an electronic component at a speed independent from a clock speed of said electrical component;

said system comprising an optical data storage component communicating with both said optical bus and said electrical component;

said optical data storage component being configured to hold data transmitted on said optical bus until said electrical component is available.

7. The system according to claim 6, wherein said storage component comprises an optical latch.

8. The system according to claim 6 wherein said optical storage component provides a dual cavity.

9. The system according to claim 6 wherein said system is provided with high index contrast.

10. The system according to claim 6 wherein said system has low loss.
