Silicon photonics: Q&A with Kotura's CTO

A Q&A with Mehdi Asghari, CTO of silicon photonics start-up, Kotura.  In part one, Asghari talks about a recent IEEE conference that included silicon photonics, the next Ethernet standard, and the merits of silicon photonics for system design.

Part 1


"Photons and electrons are like cats and dogs. Electrons are dogs: they behave, they stick by you, they are loyal, they do exactly as you tell them, whereas cats are their own animals and they do what they like. And that is what photons are like."

Mehdi Asghari, CTO of Kotura

Luxtera's 100 Gigabit silicon photonics chip

Luxtera has detailed a 4x28 Gigabit optical transceiver chip. The silicon photonics company is aiming the device at embedded applications such as system backplanes and high-performance computing (HPC). The chip is also being used by Molex for 100 Gigabit active optical cables. Molex bought Luxtera's active optical cable business in January 2011.


“Do I want to invest in a copper backplane for a single generation or do I switch over now to optics and have a future-proof three-generation chassis?”  

Marek Tlalka, Luxtera
