engineering at dtu fotonik

Welcome to DTU Fotonik. We are the department of Photonics Engineering. Our research - which is available to our students - covers almost the entire field of photonics, from communication technologies, via lighting to nanophotonics.

Read about the educational lines that we manage and contribute to.

Metamaterials are designed structures with characteristics that are not yet found in nature. These characteristics can lead to super high definition images, to render materials transparent i relation to light, to improving photovoltaic cells, to unveil new types of waves (for instance bulk plasmons), etc.

Theoretical simulation

By utilizing photonic crystal technology, it is possible to produce a compact component which splits a ray of light in two. To the right you see an electron microsope image of the fabricated component which has a typical distance of 400 nanometers between the holes. To the left you can see a theoretical simulaton of the light which comes in from the left and is split in two.

LED light on the Danish Crown Jewels

Improved illumination of the Crown Jewels

We are illuminating the Danish crown jewels with an LED system developed at DTU Fotonik. This lighting system shows off the colors perfectly and also maintains a temperature that does not harm the priceless objects. The LED system is both far cheaper and much more environmentally safe than the previous lighting set-up.
