POINTS OF DISCUSSION LITERATURE SURVEY INTRODUCTION BLOCK DIAGRAM SMART PIXEL ARRAY COMPONENTS MODULATOR PROCESSING ELEMENT (PE) ARRAY PHOTO RECEIVER APPLICATIONS CONCLUSIONS FUTURE DIRECTIONS

LITERATURE SURVEY High Speed Communication High Bandwidth Less Interference Less Weight Less Power

INTRODUCTION Optoelectronic Integrated Circuits (OEICs) Interconnections in Digital Systems  Backplane Communications  Board-to-Board Communications

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.
