Introduction

MEMS became a force in optical telecom in late 1990’s

– Large scale Optical Cross Connect Switches

– Passive Silicon Optical Benches

– Optical Attenuators

2000 – Days of the M&A

– Xros/Nortel: $3.25B

– Coretek/Nortel: $900M

– Cronos/JDSU: CHECK

2002 – Days of the Shutdown

– Xros: closed

– Coretek: closed

– Cronos: sold to MEMSCap for $10M

However, several Optical MEMS efforts have thrived

Optical Attenuators

Nature of fiber is that different wavelengths are attenuated at

different rates through a fiber

“Water Curve”

Page 7: Top Ten Ways to Commercialize Microtechnology

Optical Attenuators

Links are also amplified @ ~80klm

Different wavelengths can be attenuated and amplified at different

gains

Tx Amplifier Amplifier Rx

Receivers must deal with large changes in power level for various

wavelengths

Page 8: Top Ten Ways to Commercialize Microtechnology

Optical Attenuators

Typical links used discrete optical attenuators to balance the power

in channels

– Typically expensive ($300 ea) and

– Require 1 - 2m of fiber

– Occupy 3-4 cm2 of board space

Market Background

• Competing Technologies (LCD, EO)• MEMS “bad rap”• Industry in survival mode

BUT:

• Customers feeling the same squeeze• Technology barriers to existing solutions

= Opportunity for MEMS

Integrated MEMS Rx

Page 10: Top Ten Ways to Commercialize Microtechnology

• The PTV/ATV 10G combines a 10Gb/s receiver with a MEMS based VOA in one package

• Enables increased density and lower cost to system vendors (density x2, CR ~300/ch)

Terminology– Everyone has to speak the same language

– 3000 word glossary (MANCEF estimate)

– MST, Micromachine, Microtechnology, Nanotechnology,

MEMS, NEMS, Microsystems!?!?!?!?!?!?!

Page 15: Top Ten Ways to Commercialize Microtechnology

#9

Reliability– Speak in terms your customer understands

Only in Canada eh?

Page 16: Top Ten Ways to Commercialize Microtechnology

#8

Standards– Again, talk in terms customers understand

– Telcordia 1221 + 468

– 3 MEMS standards, 100+ semiconductor standards

Page 17: Top Ten Ways to Commercialize Microtechnology

#7

Specifications– Again, talk in terms customers understand

Be careful of spec creep!

Page 18: Top Ten Ways to Commercialize Microtechnology

#6

Look for places where small tech works

but other technologies don’t!– LCD, EO competitors!

Page 19: Top Ten Ways to Commercialize Microtechnology

#5

Integrate with technologies that are

proven!

Page 20: Top Ten Ways to Commercialize Microtechnology

#4

Need to provide a REAL benefit: cost?

Performance? Size?

Page 21: Top Ten Ways to Commercialize Microtechnology

#3

Set realistic expectations with customers.

Remember: MEMS Inside doesn’t sell!

Conclusion

Integrated devices offer significant space and cost savings

Integration offers design challenges with additional DOF

MEMS Solution viable for unique applications

– Other solutions don’t fit!

Combination of design tools and shortloop experiments

enabled faster TTM

Successful implementation of MEMS by:

– Adapting technology to the required solution

– Identify the market need and design the MEMS to fit the need

A significant challenge to the widespread acceptance of

“small tech” is the lack of a sound reliability model
