<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 />

Conventional Per-Channel<br />

WDM Filtering<br />

1Tb/s<br />

Guard bands allow for individual<br />

wavelength demux<br />

Limits channel density and fiber capacity<br />

Limits data rates by limiting available<br />

spectrum for modulation bandwidth<br />

Multi-Carrier FlexChannel<br />

1Tb/s<br />

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

channel ( FlexCoherent)<br />

Up to 25% increase in useable amplifier<br />
