SMART PIXEL ARRAY
BLOCK DIAGRAM
SMART PIXEL ARRAY COMPONENTS Modulator Multiple-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.
