Want to help rethink the foundation of the internet? Become a PhD student at DTU Electro

it only takes 20 minutes! The internet is growing at an explosive pace - and so is its energy consumption. Yet light is still the most energy-efficient way to transmit information. Today, data is sent around the globe as billions of light pulses every second, generated by millions of individual lasers.

We have shown that many of these lasers can be replaced by a single optical light source that emits a full rainbow spectrum of colours - and that each colour can act as its own “mini-laser”. In other words: one light source can do the job of many, making communication systems far more energy-efficient. This is exactly the technology we are developing.

And as a PhD student, you will play a key role in turning this concept into reality. What will you be working on? You will join an international research environment developing new ways of transmitting data - more energy-efficiently, more scalably, and with fewer active components.

Your main responsibilities include

- Working on a project that combines photonics, modelling, chip design and hands-on experiments - in a field that is advancing rapidly. - Contributing both independently and as part of a close-knit team where we support each other, share ideas, and lift the projects together1 …
