BLOCK DIAGRAM

SMART PIXEL ARRAY COMPONENTS

• ModulatorMultiple-quantum-well (MQW)

modulators Vertical-Cavity Surface-Emitting

Lasers(VCSELs)• Processing Element (PE) Array• Photo Receiver Array

MODULATOR

Vertical Cavity Surface Emitting Laser (VCSEL)

Accurate wavelength control Improved reliability Reduced operating current Narrow circular output beam

PROCESSING ELEMENT (PE) ARRAY

• It is 1-bit wide processor• An arithmetic logic unit• A full adder • A 32-bit shift-register • 6 static registers

PHOTO RECEIVER ARRAY

• Photodiode• current mirror amplifier• Two voltage comparators

SMART PIXEL ARRAY MODULE

APPLICATIONS

• Telecommunication-data communication switching networks (e.g., ATM switches)

• Fine-grained parallel computers.

CONCLUSIONS

• Data retrieval rates could improve• Parallel error detection and correction

FUTURE DIRECTIONS

• More compact packaging • Scale the SPAs to larger array dimensions.
