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

UNIC silicon modulator

Kotura has detailed a compact, low-power silicon-based optical modulator; an important building block to enable dense on-chip optical interconnects. The modulator operates at up to 11Gbit/s, consumes 0.5mW and has an area of 1000µm².

This is the silicon photonic start-up’s first announced modulator. The design has been developed in conjunction with Sun Microsystems as part of the DAPRA Ultraperformance Nanophotonic Intrachip Communications (UNIC) programme.
