  2. HIGH SPEEDSMART PIXEL ARRAYS Guided by, Presenting by, Mr. RANJITH.C SHAHID.C & ROLL NO: 63 Ms. KAVYA.K.M REG. NO: CTAHEEC130

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

  4. LITERATURE SURVEY • High Speed Communication • High Bandwidth • Less Interference • Less Weight • Less Power

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

  6. SMART PIXEL ARRAY

  7. BLOCK DIAGRAM

  8. SMART PIXEL ARRAY COMPONENTS • Modulator • Multiple-quantum-well (MQW) modulators • Vertical-Cavity Surface-Emitting Lasers(VCSELs) • Processing Element (PE) Array • Photo Receiver Array

  9. MODULATOR Vertical Cavity Surface Emitting Laser (VCSEL) • Accurate wavelength control • Improved reliability • Reduced operating current • Narrow circular output beam

  10. 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

  11. PHOTO RECEIVER ARRAY • Photodiode • current mirror amplifier • Two voltage comparators

  12. SMART PIXEL ARRAY MODULE

  13. APPLICATIONS • Telecommunication-data communication switching networks (e.g., ATM switches) • Fine-grained parallel computers.

  14. CONCLUSIONS • Data retrieval rates could improve • Parallel error detection and correction

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

  16. BIBLIOGRAPHY • ‘Progress and prospects of long wavelength VCSELs’ Connie J. Chang-Hasnain ,University of California, IEEE Optical Communication • www.tipmagazine.com/tip/INPHFA/vol-5/iss-3/p9.pdf
