<strong>The</strong> Inevitability <strong>of</strong> Photonic Integration<br />
“Photonic integration is <strong>the</strong> optical industry’s best hope for<br />
scaling to meet future bandwidth requirements while<br />
similarly reducing cost per bit.”<br />
Sterling Perrin, Heavy Reading<br />
“Optical integration is becoming a necessity because <strong>of</strong> 40<br />
and 100 Gigabit [transmission]…<strong>The</strong> modulation formats<br />
require you to deal with signals in parallel, and using nonintegrated<br />
components explodes <strong>the</strong> complexity.”<br />
Joe Berthold, VP Optical Architecture, Ciena<br />
“Integration is a key part <strong>of</strong> our thinking… Bandwidth growth<br />
is forcing us to consider architectures not considered before.”<br />
Sam Bucci, vice president, WDM, Alcatel-Lucent’s optics activities
<strong>The</strong> Inevitability <strong>of</strong> Photonic Integration<br />
“<strong>Infinera</strong> really does stand alone in large-scale optoelectronic<br />
integration today, with a PIC that could very<br />
well have an astounding lead time <strong>of</strong> four years over <strong>the</strong><br />
rest <strong>of</strong> <strong>the</strong> optical industry.”<br />

Limits channel density and fiber capacity<br />
Limits data rates by limiting available<br />

Tighter spacing, or higher data rate per<br />
