ECE 135 – Group 3 Presentation 3

This presentation by Kevin Parker, Pat Cleary, and Bryan Chavez, dated February 3, 2005, summarizes research into Vertical-Cavity Surface-Emitting Lasers (VCSELs) and Photodetectors (PDs). It includes a Four Corners analysis for various candidate VCSELs and outlines steps for contacting vendors, beginning optical link budgeting, and a GANTT chart for project management. Key standards, including eye-safe limits and extinction ratios, guide the analysis and future work. Relevant data sheets for VCSELs are also provided for reference.

Presentation Transcript

  1. ECE 135 – Group 3 Presentation 3 Kevin Parker with Pat Cleary & Bryan Chavez February 3rd, 2005

  2. Work Summary • Further Research into VCSEL/PDs • Four Corners Analysis for multiple candidate VCSELs • Contact vendors • Begin Optical Link Budgeting

  3. GANTT Chart

  4. Background Work for Four Corners • Eye safe limit → Pmax = 1 mW • From the 802.3 standard → extinction ratio = 9dB • Thus we see that Pmin = Pmax *10^(-9/10) • Pmin = .12589 mW

  5. VCSEL Four Corner Analysis (A) TTR-D1

  6. VCSEL Four Corner Analysis (B) HFE438x-521

  7. VCSEL Four Corner Analysis (C) HFE439x-521

  8. VCSEL Four Corner Analysis (D) VG1A-7000

  9. VCSEL Four Corner Analysis (E) KLD085VC

  10. VCSEL Four Corner Analysis (F) LV1001-TO

  11. VCSEL Four Corner Summary
