More and more via the internet and ever faster. Thanks in part to research by Jochem Verbist, it can be done

(02-07-2021) In his PhD, Jochem Verbist investigates how better and more compact transceivers for optical connections can be realised for data centres.

Few inventions have had such an impact on our lives in the last decades as the internet with applications such as streaming services, cloud storage, social media, online gaming and video conferencing. The vast majority of these applications are provided by data centres.

These are buildings the size of one or more department stores full of servers and switches, each interconnected via (almost exclusively) optical data cables. These data centres are typically owned by the big tech giants such as Amazon, Google, Facebook and Microsoft.

Because we produce and consume more data year after year, this infrastructure must be continuously expanded to support the enormous growth. This not only requires designing faster and faster optical transmitters and receivers, but also making them more compact and power efficient per bit transported.

"In my PhD, I investigate how such compact transceivers for low-power optical links can be realised using silicon-based photonic integrated circuits operating at speeds from 100 Gb/s to over 200 Gb/s per wavelength," Jochem concludes.
