Silicon Photonics: Widespread Usage on Active Components Doubtful

September, 2014

While the amount of industry chatter about silicon photonics rose substantially in 2014, partially because of certain market research firms looking to sell more reports, the technological hurdles, especially with insertion loss, make extensive use of active, combined components, such as for modulators and photodetectors, unlikely in the foreseeable future. Although there have definitely been numerous demonstrations of integrating with these CMOS fabrication processes, like with receivers, both the performance and cost are superior with standard methods. Certainly for passive devices, silicon lends itself quite well to integration, including for AWGs. Instead of using micro optics, combining waveguides with attenuators is being accomplished with Si. With 100G receivers, the delay lines are being integrated with the phase combiners...

Juniper’s Aurrion Buyout: Tech Nightmare?

August, 2016

Juniper Networks probably had very good reasons for becoming more vertically integrated in the optical space including perhaps the need to internally control its supply of transceivers as well as maybe strengthen its competitive position by acquiring intellectual property. Yet, its purchase of Aurrion and its complex set of moving parts at what seems to be a rather handsome price for the componentry company’s investors appears even more questionable than the router firm's previous pickup of BTI Systems. Aurrion’s focus is on wafer integration, the same type of technology that Intel has struggled to commercialize in the past. Although once again, following the industry in
