Key Conference 2006 12 – 13 November 2006 Telecom-grade Diode Lasers for Industrial Laser Applications Toby Strite Manager of High Power Laser Marketing Outline Evolution of Industrial Diode Lasers – Telecom-grade and beyond Diode/Fiber-based Industrial Lasers 2 © 2006 JDSU. All rights reserved. Fiber-coupled Industrial Diode Laser Eras Reliability (inception 2003) “$$$’s and *#&%^!!” – DPSS is considered technology of the future (“always has been, always will be…”) – Diode laser investment focused in telecom – Unreliable, low brightness bars are only choice Telecom-grade (2003 ?) “$/Watt” – Telecom migrants disrupt brightness, drive $/Watt – Even low-end bars reliably deliver 10,000hrs – Reliability and $/Watts begin to de-couple 3 © 2006 JDSU. All rights reserved. What is a Telecom-Grade Diode Laser? Operational Excellence and Business Breadth – Large, fully-absorbed fab (ISO-9001 a decade ago, now TL-9000) – High-volume off-shore assembly Technical and Cost Roadmaps, Extensive Track Record – Platforms, not just products Predictable, sustained performance – Rigorous NPI, PCN and PDN processes – Reliability understanding surpasses the qualification report … Confidence and Transparency for the Customer! 4 © 2006 JDSU.

Telecom 980nm pump lasers since 1993… 90mW 980nm pumps assembled in Boston sold for $7000 Five chips, several packages, one transfer to China later… – 500mW 980nm pumps sell well below $1000 – 90mW 980nm pumps cost $300 – and 980nm pump vendors are (again) profitable Over 13yrs, innovation and focused cost-reduction realized – 21% annual price reduction for 90mW part – 15% annual power increase for 980nm pumps – 26% annual $/mW price reduction to the market 5 © 2006 JDSU.
